Trait Key 

pub trait Key: Value {
    // Required method
    fn compare(data1: &[u8], data2: &[u8]) -> Ordering;
}

Trait which allows the type to be used as a key in a redb table

Required Methods

fn compare(data1: &[u8], data2: &[u8]) -> Ordering

Compare data1 with data2

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.
