Enum FrameMessageKind

pub enum FrameMessageKind {
    Publish,
    Notification,
    Request,
    Response,
}

Semantic kind of a native uProtocol frame.

This is the native-frame vocabulary. The numeric wire codes used by frame codecs and ABI profiles are defined by FrameMessageKind::wire_code; the mapping to the legacy UMessageType is an explicit projection (see FrameMessageKind::from_legacy_type).

Variants

Publish

An event published to a topic.

Notification

A directed notification to one consumer.

Request

An RPC request.

Response

An RPC response.

Implementations

impl FrameMessageKind

pub fn wire_code(self) -> u8

Gets the normative UFrame wire code of this kind.

Codes are defined by the UFrame specification: 1 = Publish, 2 = Request, 3 = Response, 4 = Notification, 0 and 5..=255 reserved. They deliberately coincide with the legacy protobuf UMessageType numbering so that projections are value-preserving, but the UFrame registry is normative from here on.

pub fn from_wire_code(code: u8) -> Option<Self>

Gets the kind denoted by a UFrame wire code.

pub fn from_legacy_type(value: UMessageType) -> Self

Projects a legacy UMessageType to a frame message kind.

pub fn to_legacy_type(self) -> UMessageType

Projects this frame message kind to the legacy UMessageType.

Trait Implementations

impl Clone for FrameMessageKind

fn clone(&self) -> FrameMessageKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameMessageKind

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

Formats the value using the given formatter.

impl Hash for FrameMessageKind

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 FrameMessageKind

fn eq(&self, other: &FrameMessageKind) -> 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.
