Struct hyper::upgrade::Upgraded

[+] Show declaration

pub struct Upgraded { /* fields omitted */ }

[−] Expand description

An upgraded HTTP connection.

This type holds a trait object internally of the original IO that was used to speak HTTP before the upgrade. It can be used directly as a Read or Write for convenience.

Alternatively, if the exact type is known, this can be deconstructed into its parts.

Implementations

impl Upgraded[−]

pub fn downcast<T: AsyncRead + AsyncWrite + Unpin + 'static>(
    self
) -> Result<Parts<T>, Self>[−]

Tries to downcast the internal trait object to the type passed.

On success, returns the downcasted parts. On error, returns the Upgraded back.

Trait Implementations

impl AsyncRead for Upgraded[+]

[+] Show hidden undocumented items

fn poll_read(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut ReadBuf<'_>
) -> Poll<Result<()>>[−]

Attempts to read from the AsyncRead into buf.

impl AsyncWrite for Upgraded[+]

[+] Show hidden undocumented items

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

Attempt to write bytes from buf into the object.

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

Like poll_write, except that it writes from a slice of buffers.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>[−]

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

fn poll_shutdown(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>[−]

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn is_write_vectored(&self) -> bool[−]

Determines if this writer has an efficient poll_write_vectored implementation.

impl Debug for Upgraded[+]

[+] Show hidden undocumented items

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

Formats the value using the given formatter.
