Struct Ref 

pub struct Ref<K, V, S = DefaultHashBuilder>
where
    K: Eq + Hash + 'static,
    V: 'static,
    S: BuildHasher + Clone + Default + 'static,
{ /* private fields */ }

A reference to an entry inside RcHashMap. Clone increments per-entry count; dropping decrements and removes the entry when it reaches zero.

Implementations

impl<K, V, S> Ref<K, V, S>

where K: Eq + Hash, S: BuildHasher + Clone + Default,

pub fn key<'a>(&'a self, map: &'a RcHashMap<K, V, S>) -> Result<&'a K, WrongMap>

Borrow the entry’s key, validating owner identity.

pub fn value<'a>( &'a self, map: &'a RcHashMap<K, V, S>, ) -> Result<&'a V, WrongMap>

Borrow the entry’s value, validating owner identity.

pub fn value_mut<'a>( &'a self, map: &'a mut RcHashMap<K, V, S>, ) -> Result<&'a mut V, WrongMap>

Mutably borrow the entry’s value, validating owner identity.

Trait Implementations

impl<K, V, S> Clone for Ref<K, V, S>

where K: Eq + Hash + 'static, V: 'static, S: BuildHasher + Clone + Default + 'static,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K, V, S> Drop for Ref<K, V, S>

where K: Eq + Hash + 'static, V: 'static, S: BuildHasher + Clone + Default + 'static,

fn drop(&mut self)

Executes the destructor for this type.

impl<K, V, S> Hash for Ref<K, V, S>

where K: Eq + Hash, S: BuildHasher + Clone + Default,

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<K, V, S> PartialEq for Ref<K, V, S>

where K: Eq + Hash, S: BuildHasher + Clone + Default,

fn eq(&self, other: &Self) -> 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<K, V, S> Eq for Ref<K, V, S>

where K: Eq + Hash, S: BuildHasher + Clone + Default,
