Trait Implementations

impl Boxed for DTrees_Split

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_SplitTrait for DTrees_Split

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

fn set_var_idx(&mut self, val: i32)

Index of variable on which the split is created.

fn set_inversed(&mut self, val: bool)

If true, then the inverse split rule is used (i.e. left and right branches are exchanged in the rule expressions below).

fn set_quality(&mut self, val: f32)

The split quality, a positive number. It is used to choose the best split.

fn set_next(&mut self, val: i32)

Index of the next split in the list of splits for the node

fn set_c(&mut self, val: f32)

< The threshold value in case of split on an ordered variable. The rule is:

fn set_subset_ofs(&mut self, val: i32)

< Offset of the bitset used by the split on a categorical variable. The rule is:

impl DTrees_SplitTraitConst for DTrees_Split

fn as_raw_DTrees_Split(&self) -> *const c_void

fn var_idx(&self) -> i32

Index of variable on which the split is created.

fn inversed(&self) -> bool

If true, then the inverse split rule is used (i.e. left and right branches are exchanged in the rule expressions below).

fn quality(&self) -> f32

The split quality, a positive number. It is used to choose the best split.

fn next(&self) -> i32

Index of the next split in the list of splits for the node

fn c(&self) -> f32

< The threshold value in case of split on an ordered variable. The rule is:

fn subset_ofs(&self) -> i32

< Offset of the bitset used by the split on a categorical variable. The rule is:

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for DTrees_Split

fn drop(&mut self)

Executes the destructor for this type.
