Type Alias bevy::asset::BoxedFuture

pub type BoxedFuture<'a, T> = Pin<Box<dyn Future<Output = T> + Send + 'a, Global>>;

An owned and dynamically typed Future used when you can’t statically type your result or need to add some indirection.

Aliased Type

struct BoxedFuture<'a, T> { /* private fields */ }

Trait Implementations

impl<P> AsyncBufRead for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncBufRead,

fn poll_fill_buf( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Result<&[u8], Error>>

Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(self: Pin<&mut Pin<P>>, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read.

impl<P> AsyncRead for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncRead,

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

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Pin<P>>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>] ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<P> AsyncSeek for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncSeek,

fn poll_seek( self: Pin<&mut Pin<P>>, cx: &mut Context<'_>, pos: SeekFrom ) -> Poll<Result<u64, Error>>

Attempt to seek to an offset, in bytes, in a stream.

impl<P> AsyncWrite for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncWrite,

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

Attempt to write bytes from buf into the object.

fn poll_write_vectored( self: Pin<&mut Pin<P>>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>] ) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.

fn poll_flush( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Result<(), Error>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Result<(), Error>>

Attempt to close the object.

impl<P> Clone for Pin<P>where P: Clone,

fn clone(&self) -> Pin<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P> Debug for Pin<P>where P: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<P> Deref for Pin<P>where P: Deref,

type Target = <P as Deref>::Target

The resulting type after dereferencing.

fn deref(&self) -> &<P as Deref>::Target

Dereferences the value.

impl<P> Display for Pin<P>where P: Display,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T, A> From<Box<T, A>> for Pin<Box<T, A>>where A: Allocator + 'static, T: ?Sized,

fn from(boxed: Box<T, A>) -> Pin<Box<T, A>>

Converts a Box<T> into a Pin<Box<T>>. If T does not implement Unpin, then *boxed will be pinned in memory and unable to be moved.

This conversion does not allocate on the heap and happens in place.

This is also available via Box::into_pin.

Constructing and pinning a Box with <Pin<Box<T>>>::from(Box::new(x)) can also be written more concisely using Box::pin(x). This From implementation is useful if you already have a Box<T>, or you are constructing a (pinned) Box in a different way than with Box::new.

impl<P> Future for Pin<P>where P: DerefMut, <P as Deref>::Target: Future,

type Output = <<P as Deref>::Target as Future>::Output

The type of value produced on completion.

fn poll( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<<Pin<P> as Future>::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl<P> Pointer for Pin<P>where P: Pointer,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<P> Stream for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: Stream,

type Item = <<P as Deref>::Target as Stream>::Item

Values yielded by the stream.

fn poll_next( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Option<<Pin<P> as Stream>::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
