OsStr in std::ffi::os_str - Rust
Description: Borrowed reference to an OS string (see `OsString`).

## OsStr

# Struct OsStr

1.87.0 · Source

    pub struct OsStr { /* private fields */ }

Expand description

Borrowed reference to an OS string (see `OsString`).

This type represents a borrowed reference to a string in the operating system’s preferred representation.

`&OsStr` is to `OsString` as `&str` is to `String`: the former in each pair are borrowed references; the latter are owned strings.

See the module’s toplevel documentation about conversions for a discussion on the traits which `OsStr` implements for conversions from/to native representations.

## Implementations§

Source§

### impl OsStr

1.0.0 (const: unstable) · Source

#### pub fn new<S: AsRef<OsStr> + ?Sized>(s: &S) -> &OsStr

Coerces into an `OsStr` slice.

##### §Examples

    use std::ffi::OsStr;

    let os_str = OsStr::new("foo");

1.74.0 · Source

#### pub unsafe fn from_encoded_bytes_unchecked(bytes: &[u8]) -> &Self

Converts a slice of bytes to an OS string slice without checking that the string contains valid `OsStr`-encoded data.

The byte encoding is an unspecified, platform-specific, self-synchronizing superset of UTF-8. By being a self-synchronizing superset of UTF-8, this encoding is also a superset of 7-bit ASCII.

See the module’s toplevel documentation about conversions for safe, cross-platform conversions from/to native representations.

##### §Safety

As the encoding is unspecified, callers must pass in bytes that originated as a mixture of validated UTF-8 and bytes from `OsStr::as_encoded_bytes` from within the same Rust version built for the same target platform. For example, reconstructing an `OsStr` from bytes sent over the network or stored in a file will likely violate these safety rules.

Due to the encoding being self-synchronizing, the bytes from `OsStr::as_encoded_bytes` can be split either immediately before or immediately after any valid non-empty UTF-8 substring.

##### §Example

    use std::ffi::OsStr;

    let os_str = OsStr::new("Mary had a little lamb");
    let bytes = os_str.as_encoded_bytes();
    let words = bytes.split(|b| *b == b' ');
    let words: Vec<&OsStr> = words.map(|word| {
        // SAFETY:
        // - Each `word` only contains content that originated from `OsStr::as_encoded_bytes`
        // - Only split with ASCII whitespace which is a non-empty UTF-8 substring
        unsafe { OsStr::from_encoded_bytes_unchecked(word) }
    }).collect();

#### pub fn to_str(&self) -> Option<&str>

Yields a `&str` slice if the `OsStr` is valid Unicode.

This conversion may entail doing a check for UTF-8 validity.

##### §Examples

    use std::ffi::OsStr;

    let os_str = OsStr::new("foo");
    assert_eq!(os_str.to_str(), Some("foo"));

1.0.0 · Source

#### pub fn to_string_lossy(&self) -> Cow<'_, str>

Converts an `OsStr` to a `Cow<str>`.

Any non-UTF-8 sequences are replaced with `U+FFFD REPLACEMENT CHARACTER`.

##### §Examples

Calling `to_string_lossy` on an `OsStr` with invalid unicode:

    // Note, due to differences in how Unix and Windows represent strings,
    // we are forced to complicate this example, setting up example `OsStr`s
    // with different source data and via different platform extensions.
    // Understand that in reality you could end up with such example invalid
    // sequences simply through collecting user command line arguments, for
    // example.

    #[cfg(unix)] {
        use std::ffi::OsStr;
        use std::os::unix::ffi::OsStrExt;

        // Here, the values 0x66 and 0x6f correspond to 'f' and 'o'
        // respectively. The value 0x80 is a lone continuation byte, invalid
        // in a UTF-8 sequence.
        let source = [0x66, 0x6f, 0x80, 0x6f];
        let os_str = OsStr::from_bytes(&source[..]);

        assert_eq!(os_str.to_string_lossy(), "fo�o");
    }
    #[cfg(windows)] {
        use std::ffi::OsString;
        use std::os::windows::prelude::*;

        // Here the values 0x0066 and 0x006f correspond to 'f' and 'o'
        // respectively. The value 0xD800 is a lone surrogate half, invalid
        // in a UTF-16 sequence.
        let source = [0x0066, 0x006f, 0xD800, 0x006f];
        let os_string = OsString::from_wide(&source[..]);
        let os_str = os_string.as_os_str();

        assert_eq!(os_str.to_string_lossy(), "fo�o");
    }

1.0.0 · Source

#### pub fn to_os_string(&self) -> OsString

Copies the slice into an owned `OsString`.

##### §Examples

    use std::ffi::{OsStr, OsString};

    let os_str = OsStr::new("foo");
    let os_string = os_str.to_os_string();
    assert_eq!(os_string, OsString::from("foo"));

1.9.0 · Source

#### pub fn is_empty(&self) -> bool

Checks whether the `OsStr` is empty.

##### §Examples

    use std::ffi::OsStr;

    let os_str = OsStr::new("");
    assert!(os_str.is_empty());

    let os_str = OsStr::new("foo");
    assert!(!os_str.is_empty());

1.9.0 · Source

#### pub fn len(&self) -> usize

Returns the length of this `OsStr`.

Note that this does not return the number of bytes in the string in OS string form.

The length returned is that of the underlying storage used by `OsStr`. As discussed in the `OsString` introduction, `OsString` and `OsStr` store strings in a form best suited for cheap inter-conversion between native-platform and Rust string forms, which may differ significantly from both of them, including in storage size and encoding.

This number is simply useful for passing to other methods, like `OsString::with_capacity` to avoid reallocations.

See the main `OsString` documentation information about encoding and capacity units.

##### §Examples

    use std::ffi::OsStr;

    let os_str = OsStr::new("");
    assert_eq!(os_str.len(), 0);

    let os_str = OsStr::new("foo");
    assert_eq!(os_str.len(), 3);

1.20.0 · Source

#### pub fn into_os_string(self: Box<Self>) -> OsString

Converts a `Box<OsStr>` into an `OsString` without copying or allocating.

1.74.0 · Source

#### pub fn as_encoded_bytes(&self) -> &[u8] ⓘ

Converts an OS string slice to a byte slice. To convert the byte slice back into an OS string slice, use the `OsStr::from_encoded_bytes_unchecked` function.

The byte encoding is an unspecified, platform-specific, self-synchronizing superset of UTF-8. By being a self-synchronizing superset of UTF-8, this encoding is also a superset of 7-bit ASCII.

Note: As the encoding is unspecified, any sub-slice of bytes that is not valid UTF-8 should be treated as opaque and only comparable within the same Rust version built for the same target platform. For example, sending the slice over the network or storing it in a file will likely result in incompatible byte slices. See `OsString` for more encoding details and `std::ffi` for platform-specific, specified conversions.

Source

#### pub fn slice_encoded_bytes<R: RangeBounds<usize>>(&self, range: R) -> &Self

🔬This is a nightly-only experimental API. (`os_str_slice` #118485)

Takes a substring based on a range that corresponds to the return value of `OsStr::as_encoded_bytes`.

The range’s start and end must lie on valid `OsStr` boundaries. A valid `OsStr` boundary is one of:

- The start of the string
- The end of the string
- Immediately before a valid non-empty UTF-8 substring
- Immediately after a valid non-empty UTF-8 substring

##### §Panics

Panics if `range` does not lie on valid `OsStr` boundaries or if it exceeds the end of the string.

##### §Example

    #![feature(os_str_slice)]

    use std::ffi::OsStr;

    let os_str = OsStr::new("foo=bar");
    let bytes = os_str.as_encoded_bytes();
    if let Some(index) = bytes.iter().position(|b| *b == b'=') {
        let key = os_str.slice_encoded_bytes(..index);
        let value = os_str.slice_encoded_bytes(index + 1..);
        assert_eq!(key, "foo");
        assert_eq!(value, "bar");
    }

#### pub fn make_ascii_lowercase(&mut self)

Converts this string to its ASCII lower case equivalent in-place.

ASCII letters ‘A’ to ‘Z’ are mapped to ‘a’ to ‘z’, but non-ASCII letters are unchanged.

To return a new lowercased value without modifying the existing one, use `OsStr::to_ascii_lowercase`.

##### §Examples

    use std::ffi::OsString;

    let mut s = OsString::from("GRÜßE, JÜRGEN ❤");

    s.make_ascii_lowercase();

    assert_eq!("grÜße, jÜrgen ❤", s);

1.53.0 · Source

#### pub fn make_ascii_uppercase(&mut self)

Converts this string to its ASCII upper case equivalent in-place.

ASCII letters ‘a’ to ‘z’ are mapped to ‘A’ to ‘Z’, but non-ASCII letters are unchanged.

To return a new uppercased value without modifying the existing one, use `OsStr::to_ascii_uppercase`.

##### §Examples

    use std::ffi::OsString;

    let mut s = OsString::from("Grüße, Jürgen ❤");

    s.make_ascii_uppercase();

    assert_eq!("GRüßE, JüRGEN ❤", s);

1.53.0 · Source

#### pub fn to_ascii_lowercase(&self) -> OsString

Returns a copy of this string where each character is mapped to its ASCII lower case equivalent.

ASCII letters ‘A’ to ‘Z’ are mapped to ‘a’ to ‘z’, but non-ASCII letters are unchanged.

To lowercase the value in-place, use `OsStr::make_ascii_lowercase`.

##### §Examples

    use std::ffi::OsString;
    let s = OsString::from("Grüße, Jürgen ❤");

    assert_eq!("grüße, jürgen ❤", s.to_ascii_lowercase());

1.53.0 · Source

#### pub fn to_ascii_uppercase(&self) -> OsString

Returns a copy of this string where each character is mapped to its ASCII upper case equivalent.

ASCII letters ‘a’ to ‘z’ are mapped to ‘A’ to ‘Z’, but non-ASCII letters are unchanged.

To uppercase the value in-place, use `OsStr::make_ascii_uppercase`.

##### §Examples

    use std::ffi::OsString;
    let s = OsString::from("Grüße, Jürgen ❤");

    assert_eq!("GRüßE, JüRGEN ❤", s.to_ascii_uppercase());

1.53.0 · Source

#### pub fn is_ascii(&self) -> bool

Checks if all characters in this string are within the ASCII range.

An empty string returns `true`.

##### §Examples

    use std::ffi::OsString;

    let ascii = OsString::from("hello!\n");
    let non_ascii = OsString::from("Grüße, Jürgen ❤");

    assert!(ascii.is_ascii());
    assert!(!non_ascii.is_ascii());

1.53.0 · Source

#### pub fn eq_ignore_ascii_case<S: AsRef<OsStr>>(&self, other: S) -> bool

Checks that two strings are an ASCII case-insensitive match.

Same as `to_ascii_lowercase(a) == to_ascii_lowercase(b)`, but without allocating and copying temporaries.

##### §Examples

    use std::ffi::OsString;

    assert!(OsString::from("Ferris").eq_ignore_ascii_case("FERRIS"));
    assert!(OsString::from("Ferrös").eq_ignore_ascii_case("FERRöS"));
    assert!(!OsString::from("Ferrös").eq_ignore_ascii_case("FERRÖS"));

1.87.0 · Source

#### pub fn display(&self) -> Display<'_>

Returns an object that implements `Display` for safely printing an `OsStr` that may contain non-Unicode data. This may perform lossy conversion, depending on the platform. If you would like an implementation which escapes the `OsStr` please use `Debug` instead.

##### §Examples

    use std::ffi::OsStr;

    let s = OsStr::new("Hello, world!");
    println!("{}", s.display());

Source

#### pub const fn as_os_str(&self) -> &OsStr

🔬This is a nightly-only experimental API. (`str_as_str` #130366)

Returns the same string as a string slice `&OsStr`.

This method is redundant when used directly on `&OsStr`, but it helps dereferencing other string-like types to string slices, for example references to `Box<OsStr>` or `Arc<OsStr>`.
