Enum NumericResponse 

pub enum NumericResponse<'a> {
    Borrowed(&'a [f64]),
    Owned(Vec<f64>),
    Weighted {
        values: NumericCol<'a>,
        weights: NumericCol<'a>,
    },
}

Response storage used by compiled formula models.

Variants

Borrowed(&'a [f64])

Borrowed response storage.

Owned(Vec<f64>)

Owned response storage.

Weighted

Response with observation weights.

Fields

values: NumericCol<'a>

Response values.

weights: NumericCol<'a>

Observation weights.

Implementations

impl NumericResponse<'_>

pub fn as_slice(&self) -> &[f64]

Returns response values as a slice.

pub fn weights(&self) -> Option<&[f64]>

Returns observation weights when present.

Trait Implementations

impl<'a> Clone for NumericResponse<'a>

fn clone(&self) -> NumericResponse<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for NumericResponse<'a>

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

Formats the value using the given formatter.

impl<'row> ObservationView<'row> for NumericResponse<'_>

type Observation = f64

Observation representation returned for one row.

fn len(&self) -> usize

Number of observations.

fn observation_at(&'row self, row: usize) -> Self::Observation

Observation value for row.

fn weight_at(&self, _row: usize) -> f64

Non-negative finite observation weight for row.

fn validate(&self) -> Result<(), ModelError>

Validates observation-level invariants before hot-path evaluation.

fn is_empty(&self) -> bool

Returns true if there are no observations.

impl<'a> PartialEq for NumericResponse<'a>

fn eq(&self, other: &NumericResponse<'a>) -> 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.
