Trait bevy::utils::PreHashMapExt

pub trait PreHashMapExt<K, V> {
    fn get_or_insert_with<F>(
        &mut self,
        key: &Hashed<K, FixedState>,
        func: F
    ) -> &mut V
    where
        F: FnOnce() -> V;
}

Extension methods intended to add functionality to PreHashMap.

Required Methods

fn get_or_insert_with<F>(
    &mut self,
    key: &Hashed<K, FixedState>,
    func: F
) -> &mut V where
    F: FnOnce() -> V, 

Tries to get or insert the value for the given key using the pre-computed hash first. If the PreHashMap does not already contain the key, it will clone it and insert the value returned by func.

Implementors

impl<K, V> PreHashMapExt<K, V> for HashMap<Hashed<K, FixedState>, V, PassHash, Global> where
    K: Hash + Eq + PartialEq<K> + Clone,
