Struct CountBitReader 

pub struct CountBitReader<E: Endianness, BR: BitRead<E>, const PRINT: bool = false> {
    pub bits_read: usize,
    /* private fields */
}

A wrapper around a BitRead that keeps track of the number of bits read and optionally prints on standard error the operations performed on the stream.

Fields

bits_read: usize

The number of bits read (or skipped) so far from the underlying BitRead.

Implementations

impl<E: Endianness, BR: BitRead<E>, const PRINT: bool> CountBitReader<E, BR, PRINT>

pub const fn new(bit_read: BR) -> Self

pub fn into_inner(self) -> BR

Consumes this reader and returns the underlying BitRead.

Trait Implementations

impl<E: Endianness, BR: BitRead<E>, const PRINT: bool> BitRead<E> for CountBitReader<E, BR, PRINT>

const PEEK_BITS: usize = BR::PEEK_BITS

The number of bits that peek_bits is guaranteed to return successfully (with zero-extended EOF).

type Error = <BR as BitRead<E>>::Error

type PeekWord = <BR as BitRead<E>>::PeekWord

The type we can read from the stream without advancing.

fn read_bits(&mut self, num_bits: usize) -> Result<u64, Self::Error>

Reads num_bits bits and returns them in the lowest bits.

fn read_unary(&mut self) -> Result<u64, Self::Error>

Reads a unary code.

fn peek_bits(&mut self, n_bits: usize) -> Result<Self::PeekWord, Self::Error>

Peeks at n bits without advancing the stream position. n must be nonzero, and at most Self::PeekWord::BITS.

fn skip_bits(&mut self, n_bits: usize) -> Result<(), Self::Error>

Skip n bits from the stream.

fn copy_to<F: Endianness, W: BitWrite<F>>( &mut self, bit_write: &mut W, n: u64, ) -> Result<(), CopyError<Self::Error, W::Error>>

impl<E: Endianness, BR: BitRead<E> + BitSeek, const PRINT: bool> BitSeek for CountBitReader<E, BR, PRINT>

type Error = <BR as BitSeek>::Error

fn bit_pos(&mut self) -> Result<u64, Self::Error>

Gets the current position in bits from the start of the stream.
