Struct Reader 

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

Pulls typed fields back out of a buffer, borrowing str/bytes zero-copy from it.

Implementations

impl<'a> Reader<'a>

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

A reader over buf, positioned at the start.

pub fn position(&self) -> usize

Bytes consumed so far.

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

Read a u8.

pub fn u16(&mut self) -> Result<u16, CodecError>

Read a u16 (little-endian).

pub fn u32(&mut self) -> Result<u32, CodecError>

Read a u32 (little-endian).

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

Read a u64 (little-endian).

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

Read a length-prefixed byte slice, borrowed from the input (zero-copy).

pub fn str(&mut self) -> Result<&'a str, CodecError>

Read a length-prefixed string, borrowed and UTF-8-validated in place.
