Struct Take

pub struct Take<T> { /* private fields */ }

The take adapter.

See: Buf::take.

Implementations

impl<T> Take<T>

pub fn left(&self) -> usize

Get the number of bytes logically left in the buffer.

This method is not the same as Buf::remaining(). It returns the maximum number of bytes the underlying buffer is allowed to have left. The returned value might be greater than the actual amount of bytes the underlying buffer has left.

pub fn set_left(&mut self, left: usize)

Set the maximum amount of bytes the underlying buffer is allowed to have.

pub fn get(&self) -> &T

Get a reference to the underlying buffer.

pub fn get_mut(&mut self) -> &mut T

Get a mutable reference to the underlying buffer.

pub fn into_inner(self) -> T

Destruct the adapter and get back the underlying buffer.

Trait Implementations

impl<T: Buf> Buf for Take<T>

fn remaining(&self) -> usize

Get the number of bytes remaining in the buffer.

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

Get the remaining bytes of the buffer as a slice.

fn advance(&mut self, n: usize)

Advance the internal cursor of the buffer by n bytes.

fn has_remaining(&self) -> bool

Check whether the buffer has any data left in it.

fn copy_to_slice(&mut self, slice: &mut [u8]) -> usize

Copy data from the buffer into slice advancing the buffer accordingly.

fn copy_to_vec(self, vec: &mut Vec<u8>)

where Self: Sized,

Available on crate feature alloc only.

Copy the buffer into vec.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Create a “by reference” adapter that takes the current instance of Buf by mutable reference.

fn reader(self) -> Reader<Self>

where Self: Sized,

Create an adapter that implements the Read and AsyncRead traits on the current instance of Buf.

fn chain<T: Buf>(self, other: T) -> Chain<Self, T>

where Self: Sized,

Create a Chain adapter that chains this buffer with other.

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

where Self: Sized,

Create a Take adapter that takes n bytes from this buffer.

impl<T: Clone> Clone for Take<T>

fn clone(&self) -> Take<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
