Trait Implementations

impl<'a, R: Unsigned> BlockSizeUser for Backend<'a, R>

type BlockSize = UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>

Size of the block in bytes.

fn block_size() -> usize

Return block size in bytes.

impl<'a, R: Unsigned> ParBlocksSizeUser for Backend<'a, R>

type ParBlocksSize = UInt<UTerm, B1>

Number of blocks which can be processed in parallel.

impl<'a, R: Unsigned> StreamBackend for Backend<'a, R>

fn gen_ks_block(&mut self, block: &mut GenericArray<u8, U64>)

Generate keystream block.

fn gen_par_ks_blocks( &mut self, blocks: &mut GenericArray<GenericArray<u8, Self::BlockSize>, Self::ParBlocksSize>, )

Generate keystream blocks in parallel.

fn gen_tail_blocks(&mut self, blocks: &mut [GenericArray<u8, Self::BlockSize>])

Generate keystream blocks. Length of the buffer MUST be smaller than Self::ParBlocksSize.
