Struct block_buffer::BlockBuffer[][src]

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

Buffer for block processing of data

Implementations

impl<BlockSize: ArrayLength<u8>> BlockBuffer<BlockSize>[src]

pub fn input_block(
    &mut self,
    input: &[u8],
    f: impl FnMut(&GenericArray<u8, BlockSize>)
)
[src]

Process data in input in blocks of size BlockSize using function f.

pub fn input_blocks(
    &mut self,
    input: &[u8],
    f: impl FnMut(&[GenericArray<u8, BlockSize>])
)
[src]

Process data in input in blocks of size BlockSize using function f, which accepts slice of blocks.

pub fn input_lazy(
    &mut self,
    input: &[u8],
    f: impl FnMut(&GenericArray<u8, BlockSize>)
)
[src]

Variant that doesn’t flush the buffer until there’s additional data to be processed. Suitable for tweakable block ciphers like Threefish that need to know whether a block is the last data block before processing it.

pub fn len64_padding_be(
    &mut self,
    data_len: u64,
    f: impl FnMut(&GenericArray<u8, BlockSize>)
)
[src]

Pad message with 0x80, zeros and 64-bit message length using big-endian byte order

pub fn len64_padding_le(
    &mut self,
    data_len: u64,
    f: impl FnMut(&GenericArray<u8, BlockSize>)
)
[src]

Pad message with 0x80, zeros and 64-bit message length using little-endian byte order

pub fn len128_padding_be(
    &mut self,
    data_len: u128,
    f: impl FnMut(&GenericArray<u8, BlockSize>)
)
[src]

Pad message with 0x80, zeros and 128-bit message length using big-endian byte order

pub fn pad_with<P: Padding>(
    &mut self
) -> Result<&mut GenericArray<u8, BlockSize>, PadError>
[src]

Pad message with a given padding P

Returns PadError if internall buffer is full, which can only happen if input_lazy was used.

pub fn size(&self) -> usize[src]

Return size of the internall buffer in bytes

pub fn position(&self) -> usize[src]

Return current cursor position

pub fn remaining(&self) -> usize[src]

Return number of remaining bytes in the internall buffer

pub fn reset(&mut self)[src]

Reset buffer by setting cursor position to zero
