Enum MessageType 

pub enum MessageType {
    NBirth,
    NDeath,
    NData,
    NCmd,
    DBirth,
    DDeath,
    DData,
    DCmd,
    State,
}

A Sparkplug message type (the topic’s message_type token).

Variants

NBirth

Edge Node birth certificate.

NDeath

Edge Node death certificate.

NData

Edge Node data.

NCmd

Edge Node command.

DBirth

Device birth certificate.

DDeath

Device death certificate.

DData

Device data.

DCmd

Device command.

State

Host Application state.

Implementations

impl MessageType

pub const fn as_str(self) -> &'static str

The wire token ("NBIRTH", "DDATA", …).

pub const fn has_device(self) -> bool

Whether this message type addresses a Device (carries a device_id).

pub const fn carries_seq(self) -> bool

Whether a payload of this type carries a sequence number. NDEATH, NCMD, DCMD, and STATE do not (tck-id-payloads-{ndeath,ncmd,dcmd}-seq).

pub const fn is_command(self) -> bool

Whether this is a command (NCMD/DCMD).

Trait Implementations

impl Clone for MessageType

fn clone(&self) -> MessageType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MessageType

impl Debug for MessageType

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

Formats the value using the given formatter.

impl Display for MessageType

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

Formats the value using the given formatter.

impl Eq for MessageType

impl FromStr for MessageType

type Err = SparkplugError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for MessageType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MessageType

fn eq(&self, other: &MessageType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
