Struct ByteReader 

pub struct ByteReader<'a> { /* private fields */ }

Cursor over a byte slice, mirroring ByteWriter.

Implementations

impl<'a> ByteReader<'a>

pub fn new(buf: &'a [u8]) -> Self

Start reading at offset 0.

pub fn position(&self) -> usize

Bytes consumed so far.

pub fn u8(&mut self) -> Result<u8, DecodeError>

One raw byte.

pub fn varint(&mut self) -> Result<u64, DecodeError>

Unsigned LEB128.

pub fn svarint(&mut self) -> Result<i64, DecodeError>

Zigzag-mapped signed LEB128.

pub fn f64(&mut self) -> Result<f64, DecodeError>

Little-endian f64.

pub fn take(&mut self, n: usize) -> Result<&'a [u8], DecodeError>

n raw bytes.

pub fn block(&mut self) -> Result<&'a [u8], DecodeError>

Length-prefixed byte block.
