Enum WaitableDataChannelRequest 

pub enum WaitableDataChannelRequest {
    Read {
        responder: WaitableDataChannelReadResponder,
    },
    Write {
        payload: WaitableDataChannelWriteRequest,
        responder: WaitableDataChannelWriteResponder,
    },
    #[non_exhaustive]
    _UnknownMethod {
        ordinal: u64,
        control_handle: WaitableDataChannelControlHandle,
        method_type: MethodType,
    },
}

Provides a bound / connected session to a particular DataChannel. New connections should use the UnboundWaitableDataChannel to open a session of this procotol. Calls to Read() on a WaitableDataChannel will operate as a non-blocking operation. Callers will need to use the event exchanged in the Bind() call to flag when data is available to read

Variants

Read

The call will return the next datagram to be read from the channel. If there is more data to be read, SIGNAL_READABLE will remain asserted after this call returns. If there is no data to be read, this call will return ZX_ERR_SHOULD_WAIT

Fields

responder: WaitableDataChannelReadResponder

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 and the caller should await SIGNAL_WRITABLE to be asserted.

Fields

payload: WaitableDataChannelWriteRequest

responder: WaitableDataChannelWriteResponder

#[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: WaitableDataChannelControlHandle

method_type: MethodType
