Enum Payload

pub enum Payload {
    Request(Request),
    Response(Response),
}

The data that is sent to and from setting handlers through the service MessageHub.

Variants

Request(Request)

The Request payload communicates actions to be taken upon the setting. These actions can be around access (get/listen) and changes (set). Note that there is not necessarily a 1:1 relationship between Request and Response defined later. It is possible a single Request will result into multiple Response that are delivered on the same MessageHub receptor.

Response(Response)

The Response payload represents the result of a Request action. Note that Response is a Result; receipients should confirm whether an error was returned and if a successful result (wich is an Option) has a value.

Trait Implementations

impl Clone for Payload

fn clone(&self) -> Payload

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Payload

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

Formats the value using the given formatter.

impl From<Payload> for Payload

fn from(payload: Payload) -> Payload

Converts to this type from the input type.

impl PartialEq for Payload

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

impl TryFrom<MessageEvent> for Payload

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: MessageEvent) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Payload> for Payload

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: Payload) -> Result<Self, Self::Error>

Performs the conversion.
