Struct HashDirectMapped 

pub struct HashDirectMapped<H = DefaultHasher> { /* private fields */ }

Direct-mapped (i.e. one-way associative) caching based on the key’s Hash implementation.

See the Indices trait’s documentation for more on associativity.

Trait Implementations

impl<H: Clone> Clone for HashDirectMapped<H>

fn clone(&self) -> HashDirectMapped<H>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<H: Debug> Debug for HashDirectMapped<H>

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

Formats the value using the given formatter.

impl<H: Default> Default for HashDirectMapped<H>

fn default() -> HashDirectMapped<H>

Returns the “default value” for a type.

impl<H: Hash> Hash for HashDirectMapped<H>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T, C, H> Indices<T, C> for HashDirectMapped<H>

where T: ?Sized + Hash, C: Capacity, H: Hasher + Default,

type Indices = Range<usize>

The iterator over indices within the range 0..C::CAPACITY yielding the slots in the cache where the key’s entry might reside.

fn indices(key: &T) -> Self::Indices

Get the indices within the range 0..C::CAPACITY representing slots in the cache where the given key’s entry might reside.

impl<H: Ord> Ord for HashDirectMapped<H>

fn cmp(&self, other: &HashDirectMapped<H>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<H: PartialEq> PartialEq for HashDirectMapped<H>

fn eq(&self, other: &HashDirectMapped<H>) -> 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.

impl<H: PartialOrd> PartialOrd for HashDirectMapped<H>

fn partial_cmp(&self, other: &HashDirectMapped<H>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
