Struct std::collections::hash_map::RawEntryBuilderMut

pub struct RawEntryBuilderMut<'a, K: 'a, V: 'a, S: 'a> {
    map: &'a mut HashMap<K, V, S>,
}

🔬This is a nightly-only experimental API. (hash_raw_entry #56167)

A builder for computing where in a HashMap a key-value pair would be stored.

See the HashMap::raw_entry_mut docs for usage examples.

Fields
