1.0.0[][src]Trait alloc::string::ToString

pub trait ToString {
    fn to_string(&self) -> String;
}

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

Converts the given value to a String.

Examples

Basic usage:

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

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

Implementors

impl ToString for String
[src]

impl ToString for str
[src]

impl<'a> ToString for Cow<'a, str>
[src]

impl<T: Display + ?Sized> ToString for T
[src]

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.
