Struct rustc_data_structures::sorted_map::SortedMap[][src]

pub struct SortedMap<K: Ord, V> {
    data: Vec<(K, V)>,
}
Expand description

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.

Fields

data: Vec<(K, V)>

Implementations

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.

Iterate over elements, sorted by key

Iterate over the keys, sorted

Iterate over values, sorted by key

Mutate all keys with the given function f. This mutation must not change the sort-order of keys.

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.

Looks up the key in self.data via slice::binary_search().
