Struct rustc_data_structures::stable_map::StableMap

source · [−]

pub struct StableMap<K, V> {
    base: FxHashMap<K, V>,
}

Expand description

A deterministic wrapper around FxHashMap that does not provide iteration support.

It supports insert, remove, get and get_mut functions from FxHashMap. It also allows to convert hashmap to a sorted vector with the method into_sorted_vector().

Fields

base: FxHashMap<K, V>
