unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res, ) -> Res
Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is unsafe in a general case as it leads to having non-exclusive mutable access to the internal data,
but it can be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place
modification is imgproc::threshold
. Read more
