Struct ExactBits 

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

MSB-first bit reader with exact end-of-data semantics (see module docs).

Implementations

impl<'a> ExactBits<'a>

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

pub fn position(&self) -> u64

Bits consumed so far.

pub fn is_dead(&self) -> bool

Whether the stream ran past the end of its data.

pub fn dead_row(&self) -> Option<usize>

The first row (of a decode_predictive call) that needed bits past the end of the data, i.e. how much of the image is real: rows from here on are frozen predictors.

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

Read n <= 25 bits.

pub fn huff(&mut self, t: &DirectHuff) -> u32

Decode one symbol.

pub fn diff(&mut self, t: &DirectHuff) -> i32

Decode one symbol + difference (exact slow path).

Trait Implementations

impl<'a> Clone for ExactBits<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
