Trait MetadataKey

pub trait MetadataKey<'a, T> {
    // Required methods
    fn to_bytes(&self) -> Vec<u8> ⓘ;
    fn from_bytes(bytes: &'a [u8]) -> Result<T>;
}

Expand description

The key of metadata.

Required Methods§

fn to_bytes(&self) -> Vec<u8> ⓘ

fn from_bytes(bytes: &'a [u8]) -> Result<T>

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.
