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