Struct bitcoin::bip158::BitStreamReader

pub struct BitStreamReader<'a, R: ?Sized> { /* private fields */ }

Bitwise stream reader.

Implementations

impl<'a, R: Read + ?Sized> BitStreamReader<'a, R>

pub fn new(reader: &'a mut R) -> BitStreamReader<'a, R>

Creates a new BitStreamReader that reads bitwise from a given reader.

pub fn read(&mut self, nbits: u8) -> Result<u64, Error>

Reads nbit bits, returning the bits in a u64 starting with the rightmost bit.

Examples

let mut reader = BitStreamReader::new(&mut input); // input contains all 1's
let res = reader.read(1).expect("read failed");
assert_eq!(res, 1_u64);
