Struct rustc_data_structures::stable_map::StableMap

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

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>

Trait Implementations

impl<K: Clone, V: Clone> Clone for StableMap<K, V>

fn clone(&self) -> StableMap<K, V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K, V> Debug for StableMap<K, V> where
    K: Eq + Hash + Debug,
    V: Debug, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K, V> Default for StableMap<K, V> where
    K: Eq + Hash, 

fn default() -> StableMap<K, V>

Returns the “default value” for a type.

impl<K, V> PartialEq<StableMap<K, V>> for StableMap<K, V> where
    K: Eq + Hash,
    V: PartialEq, 

fn eq(&self, other: &StableMap<K, V>) -> bool

    K: Eq + Hash,
    V: Eq, 

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
