Struct RangeDecoder 

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

Range coder (arithmetic decoder) for entropy decoding.

Implementations

impl<'a> RangeDecoder<'a>

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

Creates a new range decoder reading from the given byte slice.

pub fn error(&self) -> bool

Whether an EOF error was encountered.

pub fn bytes_read(&self) -> usize

Number of bytes read so far.

pub fn init(&mut self)

Initializes the decoder by reading the first 4 bytes.

pub fn decode_bit(&mut self) -> bool

Decodes a single bit.

pub fn decode_with_model(&mut self, model: &mut RCQsModel) -> u32

Decodes a symbol using a probability model.

pub fn decode_uint(&mut self, n: i32) -> u32

Decodes an n-bit unsigned integer (0 <= result < 2^n).

pub fn decode_ulong(&mut self, n: i32) -> u64

Decodes a 64-bit unsigned integer with n bits.
