Struct block_buffer::LazyBlockBuffer

pub struct LazyBlockBuffer<BlockSize: ArrayLength<u8>> { /* fields omitted */ }

Buffer for lazy block processing of data.

Implementations

impl<BlockSize: ArrayLength<u8>> LazyBlockBuffer<BlockSize>

pub fn pad_zeros(&mut self) -> &mut Block<BlockSize>

Pad remaining data with zeros and call compress with resulting block.

pub fn size(&self) -> usize

Return size of the internall buffer in bytes.

pub fn remaining(&self) -> usize

Return number of remaining bytes in the internall buffer.

pub fn reset(&mut self)

Reset buffer by setting cursor position to zero.

pub fn get_pos(&self) -> usize

Return current cursor position.

pub fn set(&mut self, buf: Block<BlockSize>, pos: usize)

Set buffer content and cursor position.

Panics

If pos is bigger or equal to block size.

Trait Implementations

impl<BlockSize: Clone + ArrayLength<u8>> Clone for LazyBlockBuffer<BlockSize>

fn clone(&self) -> LazyBlockBuffer<BlockSize>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<BlockSize: Default + ArrayLength<u8>> Default for LazyBlockBuffer<BlockSize>

fn default() -> LazyBlockBuffer<BlockSize>

Returns the “default value” for a type.

impl<B: ArrayLength<u8>> DigestBuffer<B> for LazyBlockBuffer<B>

fn digest_blocks(&mut self, input: &[u8], compress: impl FnMut(&[Block<B>]))

Digest data in input in blocks of size BlockSize using the compress function, which accepts slice of blocks.

fn reset(&mut self)

Reset buffer by setting cursor position to zero.
