Implementations

impl Buffer

pub fn null() -> Self

pub fn read(&self) -> Option<&[u8]>

read provides a reference to the included data to be parsed or copied elsewhere data is only guaranteed to live as long as the Buffer (or the scope of the extern “C” call it came from)

pub fn read_mut(&mut self) -> Option<&mut [u8]>

read_mut provides a reference to the included data to be parsed or copied elsewhere data is only guaranteed to live as long as the Buffer (or the scope of the extern “C” call it came from)

pub fn from_vec(v: Vec<u8>) -> Self

this releases our memory to the caller

pub fn from_vec_mut(v: &mut Vec<u8>) -> Self

this share our memory to the caller
