Struct SparseGradient 

pub struct SparseGradient {
    pub indices: Vec<usize>,
    pub values: Vec<f64>,
    pub original_len: usize,
}

Sparse gradient representation after top-k sparsification.

Fields

indices: Vec<usize>

Indices of the non-zero (kept) elements in the original gradient vector.

values: Vec<f64>

Values at the kept indices.

original_len: usize

Length of the original (dense) gradient vector.

Trait Implementations

impl Clone for SparseGradient

fn clone(&self) -> SparseGradient

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseGradient

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SparseGradient

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SparseGradient

fn eq(&self, other: &SparseGradient) -> 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 SparseGradient

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
