Trait Key

pub trait Key:
    Copy
    + PartialEq
    + Ord
    + Default
    + Debug {
    type Bytes: AsRef<[u8]>;

    // Required methods
    fn into_bytes(self) -> Self::Bytes;
    fn from_bytes(bytes: Self::Bytes) -> Self;
}

Required Associated Types

type Bytes: AsRef<[u8]>

Required Methods

fn into_bytes(self) -> Self::Bytes

fn from_bytes(bytes: Self::Bytes) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
