Trait Implementations

impl AbsDiffEq for SparseFeatures

type Epsilon = f32

Used for specifying relative comparisons.

fn default_epsilon() -> Self::Epsilon

The default tolerance to use when testing values that are close together.

fn abs_diff_eq(&self, other: &Self, epsilon: Self::Epsilon) -> bool

A test for equality that uses the absolute difference to compute the approximate equality of two numbers.

fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool

The inverse of AbsDiffEq::abs_diff_eq.

impl AsInner<SparseFeatures> for Features<'_>

fn as_inner(&self) -> Option<&SparseFeatures>

fn as_inner_mut(&mut self) -> Option<&mut SparseFeatures>

impl Clone for SparseFeatures

fn clone(&self) -> SparseFeatures

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseFeatures

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

Formats the value using the given formatter.

impl Default for SparseFeatures

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a mut SparseFeatures> for Features<'a>

fn from(f: &'a mut SparseFeatures) -> Features<'a>

Converts to this type from the input type.

impl From<SparseFeatures> for Features<'_>

fn from(f: SparseFeatures) -> Self

Converts to this type from the input type.

impl PartialEq for SparseFeatures

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

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

const 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 PoolReturnable<SparseFeatures> for CBAdfFeatures

fn clear_and_return_object(self, pool: &Pool<SparseFeatures>)

impl PoolReturnable<SparseFeatures> for Features<'_>

fn clear_and_return_object(self, pool: &Pool<SparseFeatures>)

impl PoolReturnable<SparseFeatures> for SparseFeatures

fn clear_and_return_object(self, pool: &Pool<SparseFeatures>)

impl TryFrom<Features<'_>> for SparseFeatures

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: Features<'_>) -> Result<Self, Self::Error>

Performs the conversion.
