Function magick_wand_terminus 

pub fn magick_wand_terminus()

This function should be called when ImageMagick is no longer needed. This function is safe to be called repeatedly.

Warning

All MagickWand, DrawingWand, and PixelWand values must be dropped before calling this function. Each wand’s Drop impl calls Destroy<Wand> on the underlying pointer, and invoking those after MagickWandTerminus has torn down the global ImageMagick environment is undefined behavior (typically a crash on process exit). If a wand is still in scope, end the scope first or call drop(wand) explicitly before calling this function.
