Methods from Deref<Target = IndexMap<Name, Primitive>>§

Source

pub fn capacity(&self) -> usize

Return the number of elements the map can hold without reallocating.

This number is a lower bound; the map might be able to hold more, but is guaranteed to be able to hold at least this many.

Computes in O(1) time.

Source

pub fn hasher(&self) -> &S

Return a reference to the map’s BuildHasher.

Source

pub fn len(&self) -> usize

Return the number of key-value pairs in the map.

Computes in O(1) time.

Source

pub fn is_empty(&self) -> bool

Returns true if the map contains no elements.

Computes in O(1) time.

Return an iterator over the key-value pairs of the map, in their order

Return an iterator over the values of the map, in their order

Source

pub fn contains_key<Q>(&self, key: &Q) -> bool
where Q: Hash + Equivalent<K> + ?Sized,

Return true if an equivalent to key exists in the map.

Computes in O(1) time (average).

where Q: Hash + Equivalent<K> + ?Sized,

Return a reference to the stored value for key, if it is present, else None.

Source

pub fn partition_point<P>(&self, pred: P) -> usize
where P: FnMut(&K, &V) -> bool,

See slice::partition_point for more details.

Source

pub fn as_slice(&self) -> &Slice<K, V>
