Struct hyper::upgrade::Upgraded

source · [−]
pub struct Upgraded { /* private fields */ }
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

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

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out. Read more

Pull some bytes from this source into the specified BufMut, returning how many bytes were read. Read more

Attempt to read from the AsyncRead into buf. Read more
