    Timeout,
    Apply(TUpgrErr),
    NegotiationFailed,
    Io(Error),
}

Error that can happen on an outbound substream opening attempt.

Io(Error)

An IO or otherwise unrecoverable error happened.

Implementations

impl<TUpgrErr> StreamUpgradeError<TUpgrErr>

pub fn map_upgrade_err<F, E>(self, f: F) -> StreamUpgradeError<E>

where F: FnOnce(TUpgrErr) -> E,

Map the inner StreamUpgradeError type.

Trait Implementations

impl<TUpgrErr> Debug for StreamUpgradeError<TUpgrErr>

where TUpgrErr: Debug,

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

Formats the value using the given formatter.

impl<TUpgrErr> Display for StreamUpgradeError<TUpgrErr>

where TUpgrErr: Error + 'static,

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

Formats the value using the given formatter.

impl<TUpgrErr> Error for StreamUpgradeError<TUpgrErr>

where TUpgrErr: Error + 'static,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
