Implementations

impl DTrees_Node

pub fn default() -> Result<DTrees_Node>

Trait Implementations

impl Boxed for DTrees_Node

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl DTrees_NodeTrait for DTrees_Node

fn as_raw_mut_DTrees_Node(&mut self) -> *mut c_void

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_class_idx(&mut self, val: i32)

Class index normalized to 0..class_count-1 range and assigned to the node. It is used internally in classification trees and tree ensembles.

fn set_parent(&mut self, val: i32)

Index of the parent node

fn set_left(&mut self, val: i32)

Index of the left child node

fn set_right(&mut self, val: i32)

Index of right child node

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.

fn set_split(&mut self, val: i32)

Index of the first split

impl DTrees_NodeTraitConst for DTrees_Node

fn as_raw_DTrees_Node(&self) -> *const c_void

fn value(&self) -> f64

Value at the node: a class label in case of classification or estimated function value in case of regression.

fn class_idx(&self) -> i32

Class index normalized to 0..class_count-1 range and assigned to the node. It is used internally in classification trees and tree ensembles.

fn parent(&self) -> i32

Index of the parent node

fn left(&self) -> i32

Index of the left child node

fn right(&self) -> i32

Index of right child node

fn default_dir(&self) -> i32

Default direction where to go (-1: left or +1: right). It helps in the case of missing values.

fn split(&self) -> i32

Index of the first split

impl Drop for DTrees_Node

fn drop(&mut self)

Executes the destructor for this type.
