Struct hyper::upgrade::Upgraded [−][src]
pub struct Upgraded { /* fields omitted */ }
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.
Methods
impl Upgraded
[src]
impl Upgraded
pub fn downcast<T: AsyncRead + AsyncWrite + 'static>(
self
) -> Result<Parts<T>, Self>
[src]
pub fn downcast<T: AsyncRead + AsyncWrite + '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.
