Trait IndexKeyed 

pub trait IndexKeyed: ProjectableIndex {
    type K: Key;
    type V: Clone + PartialEq;

    // Required method
    fn encode_value(&self, v: &Self::V) -> DbResult<Vec<u8>>;

    // Provided method
    fn encode_key(k: &Self::K) -> Vec<u8>  { ... }
}

Associated key/value types for typed row/key helpers.

Required Associated Types

type K: Key

type V: Clone + PartialEq

Required Methods

fn encode_value(&self, v: &Self::V) -> DbResult<Vec<u8>>

Provided Methods

fn encode_key(k: &Self::K) -> Vec<u8>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
