Utilities for the `str` primitive type.

## Modules§

patternExperimental
  The string Pattern API.

## Structs§

Bytes
  An iterator over the bytes of a string slice.
CharIndices
  An iterator over the `char`s of a string slice, and their positions.
Chars
  An iterator over the `char`s of a string slice.
EncodeUtf16
  An iterator of `u16` over the string encoded as UTF-16.
EscapeDebug
  The return type of `str::escape_debug`.
EscapeDefault
  The return type of `str::escape_default`.
EscapeUnicode
  The return type of `str::escape_unicode`.
Lines
  An iterator over the lines of a string, as string slices.
LinesAnyDeprecated
  Created with the method `lines_any`.
MatchIndices
  Created with the method `match_indices`.
Matches
  Created with the method `matches`.
ParseBoolError
  An error returned when parsing a `bool` using `from_str` fails
RMatchIndices
  Created with the method `rmatch_indices`.
RMatches
  Created with the method `rmatches`.
RSplit
  Created with the method `rsplit`.
RSplitN
  Created with the method `rsplitn`.
RSplitTerminator
  Created with the method `rsplit_terminator`.
Split
  Created with the method `split`.
SplitAsciiWhitespace
  An iterator over the non-ASCII-whitespace substrings of a string, separated by any amount of ASCII whitespace.
SplitInclusive
  An iterator over the substrings of a string, terminated by a substring matching to a predicate function Unlike `Split`, it contains the matched part as a terminator of the subslice.
SplitN
  Created with the method `splitn`.
SplitTerminator
  Created with the method `split_terminator`.
SplitWhitespace
  An iterator over the non-whitespace substrings of a string, separated by any amount of whitespace.
Utf8Chunk
  An item returned by the `Utf8Chunks` iterator.
Utf8Chunks
  An iterator used to decode a slice of mostly UTF-8 bytes to string slices (`&str`) and byte slices (`&[u8]`).
Utf8Error
  Errors which can occur when attempting to interpret a sequence of `u8` as a string.

## Traits§

FromStr
  Parse a value from a string

## Functions§

from_boxed_utf8_unchecked⚠

from_utf8_mut
  Converts a mutable slice of bytes to a mutable string slice.
from_utf8_unchecked⚠
  Converts a slice of bytes to a string slice without checking that the string contains valid UTF-8.
from_utf8_unchecked_mut⚠
  Converts a slice of bytes to a string slice without checking that the string contains valid UTF-8; mutable version.
from_raw_parts⚠Experimental
  Creates a `&str` from a pointer and a length.
from_raw_parts_mut⚠Experimental
  Creates a `&mut str` from a pointer and a length.
