    pub sender_id: u32,
    pub transition_id: u32,
    pub args_length: u32,
    pub args: ByteBuf,
}

Control plane message that travels on Stream 0.

Fields

opcode: u16

Opcode (see gbp_core::ControlOpcode).

request_id: u32

Request identifier (echoed in ACK / NACK).

sender_id: u32

Sender’s member id.

transition_id: u32

Related transition_id.

args_length: u32

Declared length of args.

args: ByteBuf

Opcode-specific CBOR arguments.

Implementations

impl ControlMessage

pub fn bare( opcode: u16, request_id: u32, sender_id: u32, transition_id: u32, ) -> ControlMessage

Builds an argument-less message.

pub fn with_args( opcode: u16, request_id: u32, sender_id: u32, transition_id: u32, args: Vec<u8>, ) -> ControlMessage

Builds a message with raw CBOR arguments.

pub fn to_cbor(&self) -> Vec<u8>

CBOR-encodes the message.

pub fn from_cbor(data: &[u8]) -> Result<ControlMessage, CodecError>

Decodes a CBOR-encoded message and validates args_length.

Trait Implementations

impl Clone for ControlMessage

fn clone(&self) -> ControlMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ControlMessage

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