Trait bevy::utils::PreHashMapExt

pub trait PreHashMapExt<K, V> {
    // Required method
    fn get_or_insert_with<F>(&mut self, key: &Hashed<K>, 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>, 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.

Object Safety

This trait is not object safe.

Implementors

impl<K, V> PreHashMapExt<K, V> for HashMap<Hashed<K>, V, PassHash>

where K: Hash + Eq + PartialEq + Clone,
