Derive Macro EventContent

#[derive(EventContent)]
{
    // Attributes available to this derive:
    #[ruma_event]
}

Generates an implementation of ruma_events::EventContent.

Also generates type aliases depending on the kind of event, with the final Content of the type name removed and prefixed added. For instance, a message-like event content type FooEventContent will have the following aliases generated:

• type FooEvent = MessageLikeEvent<FooEventContent>
• type SyncFooEvent = SyncMessageLikeEvent<FooEventContent>
• type OriginalFooEvent = OriginalMessageLikeEvent<FooEventContent>
• type OriginalSyncFooEvent = OriginalSyncMessageLikeEvent<FooEventContent>
• type RedactedFooEvent = RedactedMessageLikeEvent<FooEventContent>
• type RedactedSyncFooEvent = RedactedSyncMessageLikeEvent<FooEventContent>

You can use cargo doc to find out more details, its --document-private-items flag also lets you generate documentation for binaries or private parts of a library.

By default, the type this macro is used on and the generated types get a #[non_exhaustive] attribute. This behavior can be controlled by setting the ruma_unstable_exhaustive_types compile-time cfg setting as --cfg=ruma_unstable_exhaustive_types using RUSTFLAGS or .cargo/config.toml (under [build] -> rustflags = ["..."]). When that setting is activated, the attribute is not applied so the types are exhaustive.
