Function interface for SDL_Storage.

Apps that want to supply a custom implementation of SDL_Storage will fill in all the functions in this struct, and then pass it to SDL_OpenStorage to create a custom SDL_Storage object.

It is not usually necessary to do this; SDL provides standard implementations for many things you might expect to do with an SDL_Storage.

This structure should be initialized using SDL_INIT_INTERFACE()

Availability

This struct is available since SDL 3.2.0.

Notes for sdl3-sys

This interface struct can be initialized with SDL_StorageInterface::new() or Default::default().
