Derive Macro ruma_api::Outgoing

#[derive(Outgoing)]
{
    // Attributes available to this derive:
    #[wrap_incoming]
    #[incoming_no_deserialize]
}

Derive the Outgoing trait, possibly generating an 'Incoming' version of the struct this derive macro is used on. Specifically, if no #[wrap_incoming] attribute is used on any of the fields of the struct, this simple implementation will be generated:

impl Outgoing for MyType {
    type Incoming = Self;
}

If, however, #[wrap_incoming] is used (which is the only reason you should ever use this derive macro manually), a new struct IncomingT (where T is the type this derive is used on) is generated, with all of the fields with #[wrap_incoming] replaced:

#[derive(Outgoing)]
struct MyType {
    pub foo: Foo,
    #[wrap_incoming]
    pub bar: Bar,
    #[wrap_incoming(Baz)]
    pub baz: Option<Baz>,
    #[wrap_incoming(with EventResult)]
    pub x: XEvent,
    #[wrap_incoming(YEvent with EventResult)]
    pub ys: Vec<YEvent>,
}

// generated
struct IncomingMyType {
    pub foo: Foo,
    pub bar: IncomingBar,
    pub baz: Option<IncomingBaz>,
    pub x: EventResult<XEvent>,
    pub ys: Vec<EventResult<YEvent>>,
}
