Struct CallbackClosureMatcher

Source 
pub struct CallbackClosureMatcher<const CB_NAME_MAX_LENGTH: usize> { /* private fields */ }
Expand description

Helps the callback macro expansion to perform callback name matching more efficiently. The current implementation hashes by callback name length, but in principle further optimizations are possible.
