        responder: HangingDataChannelReadResponder,
    },

        responder: HangingDataChannelWriteResponder,

    },
}

Provides a bound / connected session to a particular DataChannel. New connections should use the UnboundHangingDataChannel to open a session of this procotol. Calls to Read() on a HangingDataChannel will operate as a Hanging-Get, only returning once data becomes available.

Variants

Read

The call will return the next datagram to be read from the channel. This call has hanging get semantics and will return once data is available.

Fields

responder: HangingDataChannelReadResponder

Write

The call will return once the data is fully committed.

If the driver is not ready for a write, it will return ZX_ERR_NO_RESOURCES

Fields

payload: HangingDataChannelWriteRequest

responder: HangingDataChannelWriteResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: HangingDataChannelControlHandle

method_type: MethodType
