Expand description
Trait which describes extendable-output functions (XOF).
Associated Types
Required methods
fn finalize_xof(self) -> Self::Reader
fn finalize_xof(self) -> Self::Reader
Retrieve XOF reader and consume hasher instance.
fn finalize_xof_reset(&mut self) -> Self::Reader
fn finalize_xof_reset(&mut self) -> Self::Reader
Retrieve XOF reader and reset hasher instance state.
Provided methods
Retrieve result into a boxed slice of the specified size and consume the hasher.
Box<[u8]>
is used instead of Vec<u8>
to save stack space, since
they have size of 2 and 3 words respectively.
