Constant fermium::hints::SDL_HINT_EVENT_LOGGING

pub const SDL_HINT_EVENT_LOGGING: &[u8];

A variable controlling whether SDL logs all events pushed onto its internal queue.

This variable can be set to the following values:

• “0”: Don’t log any events (default)
• “1”: Log all events except mouse and finger motion, which are pretty spammy.
• “2”: Log all events.

This is generally meant to be used to debug SDL itself, but can be useful for application developers that need better visibility into what is going on in the event queue. Logged events are sent through SDL_Log, which means by default they appear on stdout on most platforms or maybe OutputDebugString on Windows, and can be funneled by the app with SDL_LogSetOutputFunction, etc.

This hint can be toggled on and off at runtime, if you only need to log events for a small subset of program execution.
