Trait Key

pub trait Key {
    // Required method
    fn to_bytes(&self) -> Vec<u8> ;
}

Trait represent [Art] key. Trait define method which convert key into byte comparable sequence. This sequence will be used to order keys inside tree.

Required Methods

fn to_bytes(&self) -> Vec<u8>

Converts key to byte comparable sequence. This sequence used to represent key inside [Art] tree.

Warning

Implementation must ensure that returned bytes vector have consistent order of bytes. E.g. key type must have same ordering guarantees as returned byte sequence.
For instance, if "abc" < "def", then "abc".to_bytes() < "def".to_bytes(). Violation of this rule is undefined behaviour and can cause panic.
