Struct Reader

pub struct Reader<'a>(/* private fields */);

Implementations

impl<'a> Reader<'a>

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

pub fn read_bit(&mut self) -> Result<bool>

Read a single bit from the spec. Implements f(1) to return a bool for convenience.

pub fn read_bits(&mut self, num_bits: u8) -> Result<u32>

Implements f(n): Unsigned n-bit number appearing directly in the bitstream. The bits are read from high to low order. See 4.10.2

pub fn read_uvlc(&mut self) -> Result<u32>

Implements uvlc(): Variable length unsigned n-bit number appearing directly in the bitstream. See 4.10.3

pub fn read_le(&mut self, num_bits: u8) -> Result<u32>

Implements le(n): Unsigned little-endian n-byte number appearing directly in the bitstream. See 4.10.4

pub fn read_leb128(&mut self) -> Result<u32>

Implements leb128(): Unsigned integer represented by a variable number of little-endian bytes. See 4.10.5

pub fn read_su(&mut self, num_bits: u8) -> Result<i32>

Implements su(n): Signed integer converted from an n bits unsigned integer in the bitstream. (The unsigned integer corresponds to the bottom n bits of the signed integer.). See 4.10.6

pub fn read_ns(&mut self, num_bits: u8) -> Result<u32>

Implements ns(n): Unsigned encoded integer with maximum number of values n (i.e. output in range 0..n-1). See 4.10.7

pub fn read_delta_q(&mut self) -> Result<i32>

Implements 5.9.13: Delta quantizer syntax.

pub fn more_data_in_bitstream(&self) -> bool

pub fn current_annexb_obu_length( &mut self, annexb_state: &mut AnnexBState, ) -> Result<Option<usize>>

Get the length of the current OBU in AnnexB format.

pub fn skip(&mut self, num_bits: u64) -> Result<()>

Skips num_bits bits.

pub fn position(&self) -> u64

pub fn read_trailing_bits(&mut self, num_bits: u64) -> Result<()>

Implements 5.3.4.

pub fn decode_unsigned_subexp_with_ref( &mut self, mx: i32, r: i32, ) -> Result<u32>

Implements 5.9.27.

pub fn decode_signed_subexp_with_ref( &mut self, low: i32, high: i32, r: i32, ) -> Result<i32>

Implements 5.9.26.

pub fn byte_alignment(&mut self) -> Result<()>

Implements 5.3.5 Byte alignment syntax

pub fn remaining_bits(&self) -> u64

Trait Implementations

impl<'a> Clone for Reader<'a>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.
