Struct ordcode::buf::ReadFromTail

pub struct ReadFromTail<'a, R>(pub &'a mut R)
 where
    R: TailReadBytes;

Adapter which implements ReadBytes for reading from the end of the buffer.

let buf = vec![11, 22, 33, 44, 55, 0, 1];
let mut reader = DeBytesReader::new(&buf);
assert_eq!(<u16>::from_reader(ReadFromTail(&mut reader), params::AscendingOrder).unwrap(), 1);

Trait Implementations

impl<'a, R> ReadBytes for ReadFromTail<'a, R> where
    R: TailReadBytes, 

pub fn peek<F, RV>(&mut self, n: usize, f: F) -> Result<RV> where
    F: FnOnce(&[u8]) -> Result<RV>, 

Peek n bytes from head

pub fn advance(&mut self, n: usize)

Advance buffer head by n bytes. n should be smaller than remaining buffer size.

pub fn remaining_buffer(&mut self) -> &[u8]

Returns view into remaining buffer

pub fn read<F, R>(&mut self, n: usize, f: F) -> Result<R> where
    F: FnOnce(&[u8]) -> Result<R>, 

Get n bytes from the beginning of buffer, advance by n bytes

pub fn is_complete(&mut self) -> Result

Check if buffer is fully consumed (empty)
