Trait KeyStrategy

pub trait KeyStrategy {
    type Key;
    type Value;
    type Pair;

    // Required methods
    fn get_key(value: &Self::Pair) -> &Self::Key;
    fn hash(key: &Self::Key) -> u32;
}

Required Associated Types

type Key

type Value

type Pair

Key value pair(or Single)

Required Methods

fn get_key(value: &Self::Pair) -> &Self::Key

e.g. Gets first tuple(Value) element from tuple

fn hash(key: &Self::Key) -> u32

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.

Implementors

where K: Hash,

type Key = K

type Value = V

type Pair = (K, V)
