Struct PartialWrite

pub struct PartialWrite<W, Ops> { /* private fields */ }

Wraps a reader and modifies its read operations according to the given iterator of PartialOps.

Implementations

impl<W, Ops> PartialWrite<W, Ops>

pub fn new(writer: W, ops: Ops) -> PartialWrite<W, Ops>

Create a new PartialWrite, wrapping the given W and modifying its io operations via the given Ops.

pub fn get_ref(&self) -> &W

Gets a reference to the underlying W.

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

Gets a mutable reference to the underlying W.

pub fn into_inner(self) -> W

Consumes this PartialWrite, returning the underlying writer.

Trait Implementations

impl<W, Ops> AsyncRead for PartialWrite<W, Ops>

where W: AsyncRead,

fn poll_read( &mut self, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<usize, Error>
