Implementations

impl<'a> NodeUpdater<'a>

pub fn new(node: &'a mut TreeNode) -> Self

pub fn value(self, value: NodeInfos) -> Self

pub fn error(self, error: f64) -> Self

pub fn metric(self, metric: f64) -> Self

pub fn output(self, output: f64) -> Self

pub fn test(self, test: usize) -> Self

pub fn left_child(self, index: usize) -> Self

pub fn right_child(self, index: usize) -> Self

pub fn leaf(self) -> Self

Detaches the node’s children. The tested feature is kept; use Self::clean_test to clear it.
