Trait MapKey 

pub trait MapKey {
    // Required method
    fn key(&self) -> Vec<&[u8]>;
}

A trait for types which can be used as map keys.

Required Methods

fn key(&self) -> Vec<&[u8]>

Return the composite key.

Dyn Compatibility

This trait is dyn compatible.

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