Trait Implementations

impl<'a, K: Clone, V: Clone, S: Clone> Clone for ReadOnlyMap<'a, K, V, S>

fn clone(&self) -> ReadOnlyMap<'a, K, V, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, K: Debug, V: Debug, S: Debug> Debug for ReadOnlyMap<'a, K, V, S>

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

Formats the value using the given formatter.

impl<'a, K, V: Eq, Q, S: BuildHasher> Index<&Q> for ReadOnlyMap<'a, K, V, S>

where K: Eq + Hash + Borrow<Q>, Q: Hash + Eq + ?Sized,

type Output = V

The returned type after indexing.

fn index(&self, key: &Q) -> &'a V

Performs the indexing (container[index]) operation.

impl<'a, K: Eq + Hash, V: PartialEq, S: BuildHasher> PartialEq for ReadOnlyMap<'a, K, V, S>

fn eq(&self, other: &ReadOnlyMap<'_, K, V, S>) -> 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.
