Implementations

source

impl<T> Compat01As03<T>

source

pub fn new(object: T) -> Self

source

pub fn get_ref(&self) -> &T

Get a reference to 0.1 Future, Stream, AsyncRead, or AsyncWrite object contained within.

source

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

Get a mutable reference to 0.1 Future, Stream, AsyncRead or AsyncWrite object contained within.

source

pub fn into_inner(self) -> T

Consume this wrapper to return the underlying 0.1 Future, Stream, AsyncRead, or AsyncWrite object.
