Enum rubble::link::data::Pdu

pub enum Pdu<'a, L> {
    DataCont {
        message: L,
    },
    DataStart {
        message: L,
    },
    Control {
        data: BytesOr<'a, ControlPdu<'a>>,
    },
}

Structured representation of a data channel PDU.

Variants

DataCont

Continuation of an L2CAP message (or empty PDU).

Fields of DataCont

message: L

DataStart

Start of an L2CAP message (must not be empty).

Fields of DataStart

message: L

Control

LL Control PDU for controlling the Link-Layer connection.

Fields of Control

data: BytesOr<'a, ControlPdu<'a>>

Implementations

impl<'a> Pdu<'a, &'a [u8]>

pub fn empty() -> Self

Creates an empty PDU that carries no message.

This PDU can be sent whenever there’s no actual data to be transferred.

impl<'a, L> Pdu<'a, L>

pub fn llid(&self) -> Llid

Returns the LLID field to use for this PDU.

impl<'a, L: FromBytes<'a> + ?Sized> Pdu<'a, L>

pub fn parse(header: Header, payload: &'a [u8]) -> Result<Self, Error>

Parses a PDU from a Header and raw payload.

Trait Implementations

impl<'a, L: Debug> Debug for Pdu<'a, L>

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

Formats the value using the given formatter.

impl<'a> From<&'a ControlPdu<'a>> for Pdu<'a, &'a [u8]>

fn from(c: &'a ControlPdu<'a>) -> Self

Performs the conversion.

impl<'a, L: ToBytes> ToBytes for Pdu<'a, L>

Serializes the payload of the PDU to bytes.

The PDU header must be constructed using Link-Layer state (and Pdu::llid).

fn to_bytes(&self, buffer: &mut ByteWriter<'_>) -> Result<(), Error>

Converts self to bytes and writes them into writer, advancing writer to point past the encoded value.
