Trait ErrorHook

pub trait ErrorHook: Send + Sync {
    // Required methods
    fn throw(&self, error: Error) -> ErrorId;
    fn clear(&self, id: &ErrorId);
}

Implements behavior that allows for global or scoped error handling.

This allows for both “throwing” errors to register them, and “clearing” errors when they are no longer valid. This is useful for something like a user interface, in which an error can be “thrown” on some invalid user input, and later “cleared” if the user corrects the input. Keeping a unique identifier for each error allows the UI to be updated accordingly.

Required Methods

fn throw(&self, error: Error) -> ErrorId

Handles the given error, returning a unique identifier.

fn clear(&self, id: &ErrorId)

Clears the error associated with the given identifier.
