pub type DispatchFn = extern "C" fn(engine: *mut c_void, callback: extern "C" fn(*mut c_void), user_data: *mut c_void) -> bool;Expand description
Function-pointer signature of the host-provided dispatcher. Matches
the C ABI of whisker_bridge_dispatch after erasing the engine
pointer type to *mut c_void (so this crate doesn’t depend on
whisker-driver-sys).
