Struct hyper::upgrade::Upgraded[−][src]

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[src]

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

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

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