Struct UseProvidedHasher

pub struct UseProvidedHasher<C: ProvidesHasher>(/* private fields */);

Implementation of BuildHasherFromFriend which requires that the peer provides the hasher, i.e. that ProvidesHasher is implemented for the peer object

Trait Implementations

impl<C: ProvidesHasher> BuildHasherFromFriend<C> for UseProvidedHasher<C>

type Hasher = <<C as ProvidesHasher>::Hasher as BuildHasher>::Hasher

The type of the hasher that will be created

fn build_hasher_from<'f>(friend: &'f C) -> Self::Hasher

where Self::Hasher: 'f,

Creates a hashing implementation

impl<C: Clone + ProvidesHasher> Clone for UseProvidedHasher<C>

fn clone(&self) -> UseProvidedHasher<C>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C: Debug + ProvidesHasher> Debug for UseProvidedHasher<C>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C: Default + ProvidesHasher> Default for UseProvidedHasher<C>

fn default() -> UseProvidedHasher<C>

Returns the “default value” for a type.

impl<C: PartialEq + ProvidesHasher> PartialEq for UseProvidedHasher<C>

fn eq(&self, other: &UseProvidedHasher<C>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
