Trait MapKey 

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

A scalar key that can be converted to the bytes used by a map index.

Required Methods

fn as_key_bytes(&self) -> Vec<u8>

Returns the key’s canonical little-endian representation.

Dyn Compatibility

This trait is dyn compatible.

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