pub trait ToString { / Required method fn to_string(&self) -> String; }
A trait for converting a value to a String.
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.
Display
ToString
Converts the given value to a String.
let i = 5; let five = String::from("5"); assert_eq!(five, i.to_string());
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.
