Enum ChannelRequest

pub enum ChannelRequest {
    Send_ {
        packets: Vec<Packet>,
        responder: ChannelSend_Responder,
    },
    Receive {
        responder: ChannelReceiveResponder,
    },
    WatchChannelParameters {
        responder: ChannelWatchChannelParametersResponder,
    },
    _UnknownMethod {
        ordinal: u64,
        control_handle: ChannelControlHandle,
        method_type: MethodType,
    },
}

A duplex channel for sending/recieving Packets. This protocol also serves as a token to keeping the Channel open. Closing this protocol (and the associated socket for BR/EDR channels) will close the underlying channel.

Variants

Send_

Send multiple packets of data over the channel. Only one Send may be pending at a time.

Fields

packets: Vec<Packet>

responder: ChannelSend_Responder

Receive

Hanging get that waits for inbound packets. Only one Receive may be pending at a time.

Fields

responder: ChannelReceiveResponder

WatchChannelParameters

For RFCOMM channels, this will not return and calls will hang indefinitely.

For BR/EDR L2CAP connection-oriented channels this will currently not return and calls will hang indefinitely. The initial channel parameters are provided in [fuchsia.bluetooth.bredr/Channel].

For LE L2CAP connection-oriented channels, the first call will immediately return the parameters of the remote side of the channel. Subsequent calls will hang until the ChannelParameters change, at which point it will return the new parameters, including those that have not changed.

Fields

responder: ChannelWatchChannelParametersResponder

_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: ChannelControlHandle

method_type: MethodType
