Struct bitstream_io::write::BitWriterBE

pub struct BitWriterBE<'a> { /* fields omitted */ }

A wrapper for writing values to a big-endian stream.

Methods

impl<'a> BitWriterBE<'a>

fn new(writer: &mut Write) -> BitWriterBE

Wraps a big-endian writer around a Write reference.

Because this is liable to make many small writes in the course of normal operation, a BufWrite is preferable for better performance.

Trait Implementations

impl<'a> BitWrite for BitWriterBE<'a>

fn write<U>(&mut self, bits: u32, value: U) -> Result<(), Error> where U: Numeric

Writes an unsigned value to the stream using the given number of bits. This method assumes that value's type is sufficiently large to hold those bits.

fn write_signed<S>(&mut self, bits: u32, value: S) -> Result<(), Error> where S: SignedNumeric

Writes a twos-complement signed value to the stream with the given number of bits. This method assumes that value's type is sufficiently large to hold those bits.

fn write_bytes(&mut self, buf: &[u8]) -> Result<(), Error>

Writes the entirety of a byte buffer to the stream. If the stream is already byte-aligned, it will often map to a faster write_all call. Otherwise it will write bytes individually in 8-bit increments.

fn byte_aligned(&self) -> bool

Returns true if the stream is aligned at a whole byte.

fn write_unary0(&mut self, value: u32) -> Result<(), Error>

Writes value number of 1 bits to the stream and then writes a 0 bit. This field is variably-sized.

fn write_unary1(&mut self, value: u32) -> Result<(), Error>

Writes value number of 0 bits to the stream and then writes a 1 bit. This field is variably-sized.

fn byte_align(&mut self) -> Result<(), Error>

Pads the stream with 0 bits until is aligned at a whole byte. Does nothing if the stream is already aligned.
