Implementations

impl<'a> ReadBuf<'a>

pub fn from(slice: &'a [u8]) -> Self

pub fn position(&self) -> usize

pub fn expect_end(&mut self) -> Result<(), ReadError>

Check if everything has been properly consumed

pub fn is_end(&self) -> bool

Check if we reach the end of the buffer

pub fn skip_bytes(&mut self, sz: usize) -> Result<(), ReadError>
