Trait DatabaseHandle 

pub trait DatabaseHandle {
    // Required method
    fn get<'a>(&'a self, key: H256) -> Option<&'a [u8]>;

    // Provided method
    fn get_with_error<'a>(&'a self, key: H256) -> Result<&'a [u8], Error> { ... }
}

An immutable database handle.

Required Methods

fn get<'a>(&'a self, key: H256) -> Option<&'a [u8]>

Get a raw value from the database.

Provided Methods

fn get_with_error<'a>(&'a self, key: H256) -> Result<&'a [u8], Error>
