Trait PreHashMapExt

pub trait PreHashMapExt<K, V> {
    // Required method
    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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
