Struct SvmNode 

pub struct SvmNode {
    pub index: i32,
    pub value: f64,
}

A single sparse feature: index:value.

In the original LIBSVM, a sentinel node with index = -1 marks the end of each instance. In this Rust port, instance length is tracked by Vec::len() instead, so no sentinel is needed.

Fields

index: i32

1-based feature index. Uses i32 to match the original C int and preserve file-format compatibility.

value: f64

Feature value.

Trait Implementations

impl Clone for SvmNode

fn clone(&self) -> SvmNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SvmNode

impl Debug for SvmNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SvmNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SvmNode

fn eq(&self, other: &SvmNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SvmNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
