bitbit提供逐位读取和写入流的函数。

读取

let r = File::open("somefile")?;
let mut br = BitReader::new(r);

let is_one = br.read_bit()?;

let byte = br.read_byte()?;

let num = br.read_bits(5)?;

使用缓冲读取器将提高性能

let r = File::open("somefile")?;
let buff_reader = BufReader::new(r);
let mut br: BitReader<_, MSB> = BitReader::new(buff_reader);

写入

let w = File::create("somefile")?;
let mut bw = BitWriter::new(w);

bw.write_bit(true)?;

bw.write_byte(0x55)?;

bw.write_bits(0x15, 5)?;

bw.pad_to_byte();

使用缓冲写入器将提高性能

let w = File::create("somefile")?;
let mut buf_writer = BufWriter::new(w);
let mut bw = BitWriter::new(&mut buf_writer);
...
buf_writer.flush();
