Struct ServoEventLoopWaker 

#[repr(C)]
pub struct ServoEventLoopWaker {
    pub wake_callback: extern "C" fn(),
}

A callback used by Servo to wake the embedder thread when Servo has new work to process. The embedder is expected to pump Servo’s event loop in response to this callback.

Safety

The embedder must ensure that:

• wake_callback is a valid C ABI function matching the signature shown.
• wake_callback remains valid for the lifetime of the Servo instance the waker is associated with.
• wake_callback does not unwind across the FFI boundary.
• wake_callback is safe to invoke from any thread, since Servo may call it from internal threads.

Fields

wake_callback: extern "C" fn()
