Trait KeyFunction 

pub trait KeyFunction<H>
where
    H: Hasher,
{
    type Key: Send + Sync + Clone + Hash + Eq + MaybeDebug + Ord;

    // Required method
    fn key(hash: &<H as Hasher>::Out, prefix: (&[u8], Option<u8>)) -> Self::Key;
}

Various re-exports from the memory-db crate.

Required Associated Types

type Key: Send + Sync + Clone + Hash + Eq + MaybeDebug + Ord

Required Methods

fn key(hash: &<H as Hasher>::Out, prefix: (&[u8], Option<u8>)) -> Self::Key

Dyn Compatibility

This trait is not dyn compatible.

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