Struct opencv::gapi::GCompileArg
source · pub struct GCompileArg { /* private fields */ }
Expand description
Represents an arbitrary compilation argument.
Any value can be wrapped into cv::GCompileArg, but only known ones (to G-API or its backends) can be interpreted correctly.
Normally objects of this class shouldn’t be created manually, use cv::compile_args() function which automatically wraps everything passed in (a variadic template parameter pack) into a vector of cv::GCompileArg objects.

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 of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance
sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold
. Read more
