fn set_value(&mut self, val: f64)
Value at the node: a class label in case of classification or estimated
function value in case of regression.

fn set_default_dir(&mut self, val: i32)
Default direction where to go (-1: left or +1: right). It helps in the
case of missing values.

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
