Enumeration with the list of the possible stream events to pass to on_connection_event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FullyNegotiatedInbound(FullyNegotiatedInbound<IP, IOI>)

Informs the handler about the output of a successful upgrade on a new inbound substream.

FullyNegotiatedOutbound(FullyNegotiatedOutbound<OP, OOI>)

Informs the handler about the output of a successful upgrade on a new outbound stream.

AddressChange(AddressChange<'a>)

Informs the handler about a change in the address of the remote.

DialUpgradeError(DialUpgradeError<OOI, OP>)

Informs the handler that upgrading an outbound substream to the given protocol has failed.

ListenUpgradeError(ListenUpgradeError<IOI, IP>)

Informs the handler that upgrading an inbound substream to the given protocol has failed.

LocalProtocolsChange(ProtocolsChange<'a>)

The local ConnectionHandler added or removed support for one or more protocols.

RemoteProtocolsChange(ProtocolsChange<'a>)

The remote ConnectionHandler now supports a different set of protocols.

Implementations
