Implementations

impl<K, V> OrdHashMap<K, V>

pub fn new() -> Self

Construct a new OrdHashMap.

pub fn with_capacity(capacity: usize) -> Self

Construct a new OrdHashMap with the given capacity.

pub fn len(&self) -> usize

impl<K: Eq + Hash + Ord, V> OrdHashMap<K, V>

pub fn bisect<Cmp>(&self, cmp: Cmp) -> Option<&V>

The first key for which the comparison returns Some(Ordering::Equal) will be returned. This method assumes that any partially-ordered keys (where cmp(key).is_none()) lie at the beginning and/or end of the distribution.

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

Return true if there is an entry for the given key in this OrdHashMap.

Drain all entries from this OrdHashMap.

pub fn drain_while<Cond>(&mut self, cond: Cond) -> DrainWhile<'_, K, V, Cond>

where Cond: Fn((&K, &V)) -> bool,

Drain all entries from this OrdHashMap.

Return a mutable Entry in this OrdHashMap.

pub fn extend<I: IntoIterator<Item = (K, V)>>(&mut self, iter: I)

Consume iter and insert all its elements into this OrdHashMap.

pub fn first(&self) -> Option<&V>

Borrow the first value in this OrdHashMap.

Borrow the value at the given key mutably, if present.

pub fn insert(&mut self, key: K, value: V) -> Option<V>

Insert a new value at key and return the previous value, if any.

pub fn iter(&self) -> Iter<'_, K, V>

Construct an iterator over keys of this OrdHashMap.

pub fn last(&self) -> Option<&V>

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

Remove an entry from this OrdHashMap and return its value, if present.

pub fn starts_with<'a, I: IntoIterator<Item = (&'a K, &'a V)>>( &self, other: I, ) -> bool

where K: Debug + 'a, V: PartialEq + 'a,

Return true if the first elements in this OrdHashMap equal those in the given iter.

where K: Debug,

Construct an owned iterator over the values in this OrdHashMap.

pub fn values(&self) -> Values<'_, K, V>

Construct an iterator over the values in this OrdHashMap.

impl<K: Eq + Hash + Ord + Debug, V> OrdHashMap<K, V>

pub fn bisect_and_remove<Cmp>(&mut self, cmp: Cmp) -> Option<(K, V)>

where Cmp: Fn(&K) -> Option<Ordering> + Copy,

Bisect this map to match and remove an entry using the provided comparison.

The first key for which the comparison returns Some(Ordering::Equal) will be returned. This method assumes that any partially-ordered keys (where cmp(key).is_none()) lie at the beginning and/or end of the distribution.
