Trait Formatter 

pub trait Formatter {
    // Required methods
    fn key(key: &[u8]) -> String;
    fn value(key: &[u8], value: &[u8]) -> String;

    // Provided methods
    fn key_value(key: &[u8], row: impl AsRef<[u8]>) -> String { ... }
    fn key_maybe_value(key: &[u8], value: Option<impl AsRef<[u8]>>) -> String { ... }
}

Formats encoded keys and values.

Required Methods

fn key(key: &[u8]) -> String

Formats a key.

fn value(key: &[u8], value: &[u8]) -> String

Formats a value. Also takes the key to determine the ty of value.

Provided Methods

fn key_value(key: &[u8], row: impl AsRef<[u8]>) -> String

Formats a key/encoded pair.

fn key_maybe_value(key: &[u8], value: Option<impl AsRef<[u8]>>) -> String

Formats a key/encoded pair, where the value may not exist.

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.
