# Trait ethcore_util::standard::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);
    }

## Associated Types

### `type Target: ?Sized`

The resulting type after dereferencing

## Required Methods

### `fn deref(&self) -> &Self::Target`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
