Expand description

A trait for converting a value to a `String`.

This trait is automatically implemented for any type which implements the `Display` trait. As such, `ToString` shouldn’t be implemented directly: `Display` should be implemented instead, and you get the `ToString` implementation for free.

## Required Methods§

1.0.0 · Source

#### fn to_string(&self) -> String

Converts the given value to a `String`.

##### §Examples

    let i = 5;
    let five = String::from("5");

    assert_eq!(five, i.to_string());

## Implementors§

1.0.0 · Source§

### impl<T> ToString for T
where T: Display + ?Sized,

#### §Panics

In this implementation, the `to_string` method panics if the `Display` implementation returns an error. This indicates an incorrect `Display` implementation since `fmt::Write for String` never returns an error itself.
