Struct BlockBuffer 

struct BlockBuffer {
    decoded: [u8; 3],
    length: usize,
    position: usize,
}

Base64 decode buffer for a 1-block input.

This handles a partially decoded block of data, i.e. data which has been decoded but not read.

Fields

decoded: [u8; 3]

3 decoded bytes from a 4-byte Base64-encoded input.

length: usize

Length of the buffer.

position: usize

Position within the buffer.

Implementations

impl BlockBuffer

const SIZE: usize = 3usize

Size of the buffer in bytes.

fn fill(&mut self, decoded_input: &[u8]) -> Result<(), Error>

Fill the buffer by decoding up to 3 bytes of decoded Base64 input.

fn take(&mut self, nbytes: usize) -> Result<&[u8], Error>

Take a specified number of bytes from the buffer.

Returns as many bytes as possible, or an empty slice if the buffer has already been read to completion.

fn is_empty(&self) -> bool

Have all of the bytes in this buffer been consumed?

Trait Implementations

impl Clone for BlockBuffer

fn clone(&self) -> BlockBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockBuffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BlockBuffer

fn default() -> BlockBuffer

Returns the “default value” for a type.
