Trait Implementations
impl StatefulHasher for Sha2_256
impl StatefulHasher for Sha2_256
The maximum Digest size for that hasher (it is stack allocated).
type Digest = Sha2Digest<<Sha2_256 as StatefulHasher>::Size>
type Digest = Sha2Digest<<Sha2_256 as StatefulHasher>::Size>
The Digest type to distinguish the output of different Hasher
implementations.
Returns the final digest.
