Trait core::ops::Sub
[−]
[src]
pub trait Sub<RHS = Self> { type Output; fn sub(self, rhs: RHS) -> Self::Output; }
The Sub
trait is used to specify the functionality of -
.
Examples
A trivial implementation of Sub
. When Foo - Foo
happens, it ends up
calling sub
, and therefore, main
prints Subtracting!
.
use std::ops::Sub; struct Foo; impl Sub for Foo { type Output = Foo; fn sub(self, _rhs: Foo) -> Foo { println!("Subtracting!"); self } } fn main() { Foo - Foo; }
Associated Types
type Output
The resulting type after applying the -
operator
