Struct tokio_util::io::CopyToBytes

source ·
pub struct CopyToBytes<S> { /* private fields */ }
Expand description

A helper that wraps a Sink<Bytes> and converts it into a Sink<&'a [u8]> by copying each byte slice into an owned Bytes.

See the documentation for SinkWriter for an example.

Implementations§

source§

impl<S> CopyToBytes<S>

source

pub fn new(inner: S) -> Self

Creates a new CopyToBytes.

source

pub fn get_ref(&self) -> &S

Gets a reference to the underlying sink.

source

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

Gets a mutable reference to the underlying sink.

source

pub fn into_inner(self) -> S

Consumes this CopyToBytes, returning the underlying sink.
