Trait EventHandler 

pub unsafe trait EventHandler {
    const WL_INTERFACE: &'static wl_interface;

    // Required method
    unsafe fn handle_event(
        &self,
        queue: &Queue,
        data: *mut u8,
        slf: &UntypedBorrowedProxy,
        opcode: u32,
        args: *mut wl_argument,
    );

    // Provided method
    fn mutable_type() -> Option<(TypeId, &'static str)> { ... }
}

An event handler that can handle raw libwayland events.

Safety

• WL_INTERFACE must be a valid wl_interface.
• mutable_type must always return the same value.

Required Associated Constants

const WL_INTERFACE: &'static wl_interface

The type of interface that can be handled by this event handler.

Required Methods

unsafe fn handle_event( &self, queue: &Queue, data: *mut u8, slf: &UntypedBorrowedProxy, opcode: u32, args: *mut wl_argument, )

Dispatches a raw libwayland event.

Safety

• slf must have an interface compatible with WL_INTERFACE.
• opcode and args must conform to an event of WL_INTERFACE.
• Any objects contained in args must remain valid for the duration of the call.
• If Self::mutable_data returns Some, then data must be &mut T where T has the type ID returned by mutable_data.

Provided Methods

fn mutable_type() -> Option<(TypeId, &'static str)>

Returns the mutable data type required by this event handler.

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.
