Struct BitBufferRead 

pub struct BitBufferRead<'a> { /* private fields */ }

Bit-level reader with JPEG 2000 0xFF byte-unstuffing.

Reads from a byte slice, automatically handling the rule that after a 0xFF byte the MSB of the next byte is ignored (stuffed).

Implementations

impl<'a> BitBufferRead<'a>

pub fn new(data: &'a [u8]) -> Self

Create a new bit reader over the given byte slice.

pub fn fill(&mut self)

Fill the internal buffer with up to 32 new bits from the byte stream.

pub fn peek(&self, n: u32) -> u32

Peek at the top n bits without consuming them (n <= 32).

pub fn advance(&mut self, n: u32)

Consume n bits from the buffer.

pub fn read(&mut self, n: u32) -> u32

Read n bits and return them as a u32 (n <= 32).

pub fn available_bits(&self) -> u32

Returns the number of valid bits currently in the buffer.

pub fn position(&self) -> usize

Returns the current byte position in the data stream.

pub fn is_unstuffing(&self) -> bool

Returns true if the previous byte read was 0xFF.

pub fn reset(&mut self, data: &'a [u8])

Reset the reader with new data.

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

Formats the value using the given formatter.
