Trait EventHandlerContext

pub trait EventHandlerContext: Sized { }

Context for an event handler.

This trait defines the set of types that may be used as additional arguments in event handler functions after the event itself.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl EventHandlerContext for Room

This event handler context argument is only applicable to room-specific events.

Trying to use it in the event handler for another event, for example a global account data or presence event, will result in the event handler being skipped and an error getting logged.

impl EventHandlerContext for Client

impl EventHandlerContext for EventHandlerHandle

impl EventHandlerContext for RawEvent

impl<T: Clone + Send + Sync + 'static> EventHandlerContext for Ctx<T>
