Trait eso::borrow::Borrow

pub trait Borrow<'a, T: 'a> {
    fn borrow(&'a self) -> T;
}

A value that can be borrowed as a generalized reference of type T.

let value = String::from("Hello World");
let reference: &str = value.borrow();

The difference to Borrow is that this trait allows you to return types that are not actually references, such as Cows:

let value = String::from("Hello World");
let reference: Cow<str> = value.borrow();

Required methods

fn borrow(&'a self) -> T

Borrow a generalized reference of type T.
