Trait core::ops::Deref 1.0.0
[−]
[src]
pub trait Deref {
type Target: ?Sized;
fn deref(&self) -> &Self::Target;
}The Deref trait is used to specify the functionality of dereferencing
operations, like *v.
Deref also enables 'Deref coercions'.
Examples
A struct with a single field which is accessible via dereferencing the struct.
use std::ops::Deref; struct DerefExample<T> { value: T } impl<T> Deref for DerefExample<T> { type Target = T; fn deref(&self) -> &T { &self.value } } fn main() { let x = DerefExample { value: 'a' }; assert_eq!('a', *x); }Run
