Struct body_image_futio::UniBodyBuf

pub struct UniBodyBuf { /* fields omitted */ }

Provides zero-copy read access to both Bytes and Mmap memory regions. Implements bytes::Buf (mmap feature only).

Trait Implementations

impl AsRef<[u8]> for UniBodyBuf

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl Deref for UniBodyBuf

type Target = [u8]

The resulting type after dereferencing.

fn deref(&self) -> &[u8]

Dereferences the value.

impl Buf for UniBodyBuf

fn remaining(&self) -> usize

Returns the number of bytes between the current position and the end of the buffer.

fn bytes(&self) -> &[u8]

Returns a slice starting at the current position and of length between 0 and Buf::remaining(). Note that this can return shorter slice (this allows non-continuous internal representation).

fn advance(&mut self, count: usize)

Advance the internal cursor of the Buf

fn bytes_vec(&'a self, dst: &mut [&'a IoVec]) -> usize

Fills dst with potentially multiple slices starting at self's current position.

fn has_remaining(&self) -> bool

Returns true if there are any more bytes to consume

fn copy_to_slice(&mut self, dst: &mut [u8])

Copies bytes from self into dst.

fn get_u8(&mut self) -> u8

Gets an unsigned 8 bit integer from self.

fn get_i8(&mut self) -> i8

fn get_i16_le(&mut self) -> i16

fn get_uint_be(&mut self, nbytes: usize) -> u64

Gets an unsigned n-byte integer from self in big-endian byte order.

fn get_uint_le(&mut self, nbytes: usize) -> u64

fn collect<B>(self) -> B where
    B: FromBuf, 

Transforms a Buf into a concrete buffer.

fn take(self, limit: usize) -> Take<Self>
