# Struct ethcore_util::standard::mem::Discriminant [−] [src]

    pub struct Discriminant<T>(_, _);

Unstable (`discriminant_value`)

: recently added, follows RFC

Opaque type representing the discriminant of an enum.

See the `discriminant` function in this module for more information.

## Trait Implementations

### `impl<T> Eq for Discriminant<T>`

### `impl<T> Hash for Discriminant<T>`

#### `fn hash<H>(&self, state: &mut H) where H: Hasher`

Feeds this value into the state given, updating the hasher as necessary.

#### `fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher`
1.3.0

Feeds a slice of this type into the state provided.

### `impl<T> Copy for Discriminant<T>`

### `impl<T> Clone for Discriminant<T>`

#### `fn clone(&self) -> Discriminant<T>`

Returns a copy of the value. Read more

#### `fn clone_from(&mut self, source: &Self)`
1.0.0

Performs copy-assignment from `source`. Read more

### `impl<T> Debug for Discriminant<T>`

#### `fn fmt(&self, fmt: &mut Formatter) -> Result<(), Error>`

Formats the value using the given formatter.

### `impl<T> PartialEq<Discriminant<T>> for Discriminant<T>`

#### `fn eq(&self, rhs: &Discriminant<T>) -> bool`

This method tests for `self` and `other` values to be equal, and is used by `==`. Read more

#### `fn ne(&self, other: &Rhs) -> bool`
1.0.0

This method tests for `!=`.

## 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`)
