Struct Upgraded

pub struct Upgraded { /* private fields */ }

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: Read + Write + 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 Debug for Upgraded

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

Formats the value using the given formatter.

impl Read for Upgraded

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

Attempts to read bytes into the buf.

impl Write for Upgraded

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

Attempt to write bytes from buf into the destination.

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.

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

Attempts to shut down this writer.

fn is_write_vectored(&self) -> bool

Returns whether this writer has an efficient poll_write_vectored implementation.
