Required methods

fn new(output_size: usize) -> Result<Self, InvalidOutputSize>

Initialize hasher state for given output size.

Returns InvalidOutputSize if output_size is equal to zero or bigger than Self::MaxOutputSize.

fn finalize_variable_core(
    &mut self,
    buffer: &mut BlockBuffer<Self::BlockSize>,
    output_size: usize,
    f: impl FnOnce(&[u8])
)

Finalize hasher and return result of lenght output_size via closure f.

output_size must be equal to output_size used during construction.
