Trait hash_db::AsHashDB

pub trait AsHashDB<H: Hasher, T> {
    fn as_hash_db(&self) -> &dyn HashDB<H, T>;
    fn as_hash_db_mut<'a>(&'a mut self) -> &'a mut (dyn HashDB<H, T> + 'a);
}

Upcast trait for HashDB.

Required methods

fn as_hash_db(&self) -> &dyn HashDB<H, T>

Perform upcast to HashDB for anything that derives from HashDB.

fn as_hash_db_mut<'a>(&'a mut self) -> &'a mut (dyn HashDB<H, T> + 'a)

Perform mutable upcast to HashDB for anything that derives from HashDB.
