Trait fuel_core::database::storage::ToDatabaseKey

pub trait ToDatabaseKey {
    type Type<'a>: AsRef<[u8]>
       where Self: 'a;

    // Required method
    fn database_key(&self) -> Self::Type<'_>;
}

Some keys requires pre-processing that could change their type.

Required Associated Types

type Type<'a>: AsRef<[u8]> where Self: 'a

A new type of prepared database key that can be converted into bytes.

Required Methods

fn database_key(&self) -> Self::Type<'_>

Coverts the key into database key that supports byte presentation.
