Trait std::convert::Into 1.0.0
[−]
[src]
pub trait Into<T> {
fn into(self) -> T;
}A conversion that consumes self, which may or may not be expensive.
Note: this trait must not fail. If the conversion can fail, use TryInto or a dedicated
method which returns an Option<T> or a Result<T, E>.
Library authors should not directly implement this trait, but should prefer implementing
the From trait, which offers greater flexibility and provides an equivalent Into
implementation for free, thanks to a blanket implementation in the standard library.
Examples
String implements Into<Vec<u8>>:
fn is_hello<T: Into<Vec<u8>>>(s: T) { let bytes = b"hello".to_vec(); assert_eq!(bytes, s.into()); } let s = "hello".to_string(); is_hello(s);Run
