Function SDL_RectEmptyFloat

pub unsafe fn SDL_RectEmptyFloat(r: *const SDL_FRect) -> bool
Available on crate feature dep_sdl3 only.
Expand description

Determine whether a floating point rectangle can contain any point.

A rectangle is considered “empty” for this function if r is NULL, or if r’s width and/or height are < 0.0f.

Note that this is a forced-inline function in a header, and not a public API function available in the SDL library (which is to say, the code is embedded in the calling program and the linker and dynamic loader will not be able to find this function inside SDL itself).

§Parameters

  • r: the rectangle to test.

§Return value

Returns true if the rectangle is “empty”, false otherwise.

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
