Trait lignin::callback_registry::ToRefThreadBoundFallback

pub trait ToRefThreadBoundFallback<C>: Sealed + Sized where
    C: CallbackSignature, {
    fn to_ref(&self) -> CallbackRef<ThreadBound, C>;
}

Provides a fallback alternative implementation to CallbackRegistration::to_ref for use in macro frameworks.

There is no limitation on the receiver’s Syncness, but in turn the resulting CallbackRef is ThreadBound.

Warning: Using this trait can unhelpfully mask the source of ThreadBound in a larger application.

If your framework supports optional Syncness annotations, consider requiring them on originally thread-bound components.

Required methods

fn to_ref(&self) -> CallbackRef<ThreadBound, C>

See CallbackRegistration::to_ref, except that this method is unconstrained and that the resulting CallbackRef is ThreadBound.
