[−][src]Struct rustc_data_structures::sorted_map::SortedMap
SortedMap
is a data structure with similar characteristics as BTreeMap but
slightly different trade-offs: lookup, insertion, and removal are O(log(N))
and elements can be iterated in order cheaply.
SortedMap
can be faster than a BTreeMap
for small sizes (<50) since it
stores data in a more compact way. It also supports accessing contiguous
ranges of elements as a slice, and slices of already sorted elements can be
inserted efficiently.
Methods
impl<K: Ord, V> SortedMap<K, V>
[src]
pub fn new() -> SortedMap<K, V>
[src]
pub fn from_presorted_elements(elements: Vec<(K, V)>) -> SortedMap<K, V>
[src]
Construct a SortedMap
from a presorted set of elements. This is faster
than creating an empty map and then inserting the elements individually.
It is up to the caller to make sure that the elements are sorted by key and that there are no duplicates.
pub fn insert(&mut self, key: K, value: V) -> Option<V>
[src]
pub fn remove(&mut self, key: &K) -> Option<V>
[src]
pub fn get<Q: ?Sized>(&self, key: &Q) -> Option<&V> where
K: Borrow<Q>,
Q: Ord,

K: Borrow<Q>,
Q: Ord,
pub fn get_mut<Q: ?Sized>(&mut self, key: &Q) -> Option<&mut V> where

pub fn clear(&mut self)
[src]
ⓘImportant traits for Iter<'a, T>pub fn iter(&self) -> Iter<(K, V)>
[src]
Iterate over elements, sorted by key
pub fn keys(&self) -> impl Iterator<Item = &K> + ExactSizeIterator
[src]
Iterate over the keys, sorted
pub fn values(&self) -> impl Iterator<Item = &V> + ExactSizeIterator
[src]
Iterate over values, sorted by key
pub fn len(&self) -> usize
[src]
pub fn is_empty(&self) -> bool
[src]
pub fn range<R>(&self, range: R) -> &[(K, V)] where
R: RangeBounds<K>,
[src]
R: RangeBounds<K>,
pub fn remove_range<R>(&mut self, range: R) where
R: RangeBounds<K>,
[src]
R: RangeBounds<K>,
pub fn offset_keys<F>(&mut self, f: F) where
F: Fn(&mut K),
[src]
F: Fn(&mut K),
Mutate all keys with the given function f
. This mutation must not
change the sort-order of keys.
pub fn insert_presorted(&mut self, elements: Vec<(K, V)>)
[src]
Inserts a presorted range of elements into the map. If the range can be inserted as a whole in between to existing elements of the map, this will be faster than inserting the elements individually.
It is up to the caller to make sure that the elements are sorted by key and that there are no duplicates.
