Trait odht::Config

pub trait Config {
    type Key;
    type Value;
    type EncodedKey: ByteArray;
    type EncodedValue: ByteArray;
    type H: HashFn;
    fn encode_key(k: &Self::Key) -> Self::EncodedKey;
    fn encode_value(v: &Self::Value) -> Self::EncodedValue;
    fn decode_key(k: &Self::EncodedKey) -> Self::Key;
    fn decode_value(v: &Self::EncodedValue) -> Self::Value;
}

This trait provides a complete “configuration” for a hash table, i.e. it defines the key and value types, how these are encoded and what hash function is being used.

Implementations of the encode_key and encode_value methods must encode the given key/value into a fixed size array. The encoding must be deterministic (i.e. no random padding bytes) and must be independent of platform endianess. It is always highly recommended to mark these methods as #[inline].
