Trait bevy_utils::PreHashMapExt

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

Extension methods intended to add functionality to PreHashMap.

Required Methods

fn get_or_insert_with<F: FnOnce() -> V>(
    &mut self,
    key: &Hashed<K>,
    func: F
) -> &mut 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: Hash + Eq + PartialEq + Clone, V> PreHashMapExt<K, V> for PreHashMap<K, V>
