Module rustc_data_structures::sorted_map
source · Modules
- A variant of
SortedMap
that preserves insertion order.
Structs
- An indexed multi-map that preserves insertion order while permitting both O(log n) lookup of an item by key and O(1) lookup by index.
SortedMap
is a data structure with similar characteristics as BTreeMap but slightly different trade-offs: lookup is O(log(n)), insertion and removal are O(n) but elements can be iterated in order cheaply.
