Type Alias EventHandler

pub type EventHandler = Box<dyn Fn(UIEvent) -> Result<UIResponse, String> + Send + Sync>;

Type alias for event handler functions.

Event handlers are functions that take a UIEvent and return a Result<UIResponse, String>. They must be thread-safe (Send + Sync) to work with the async runtime.

Aliased Type
