pub struct ByteReader<R> { /* private fields */ }

Implementations

impl<E, R: Iterator<Item = Result<u8, E>>> ByteReader<R>

pub fn new(read: R) -> Result<Self, E>

Construct a new ByteReader from an iterator of u8

pub fn print_remaining(&mut self)

Print the remaining data

Trait Implementations

impl<E, R: Iterator<Item = Result<u8, E>>> BitReader for ByteReader<R>

type Error = E

fn peek(&self, bits: u8) -> Option<u16>

look at the next (up to 16) bits of data

fn consume(&mut self, bits: u8) -> Result<(), E>

Consume the given amount of bits from the input.

fn bits_to_byte_boundary(&self) -> u8

fn expect(&mut self, bits: Bits) -> Result<(), Option<Bits>>

Assert that the next bits matches the given pattern.
