Struct ColIdx 

pub struct ColIdx(/* private fields */);

Index into the user-facing design matrix data: Array2<f64> — i.e. the position of a covariate column in the raw input frame, before any per-family basis expansion or intercept/parametric layout is applied.

Distinct from:

• BasisIdx — term-local basis-function ordinal k of B_k(x).
• SmoothTermIdx — position in TermCollectionSpec::smooth_terms.
• A coefficient-vector offset β[i] — spans the combined design after expansion, which is much wider than the user-facing data matrix.

Keeping this as its own #[repr(transparent)] newtype rules out the easy confusion of indexing the raw data frame with an expanded-column offset.

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColIdx

impl Debug for ColIdx

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ColIdx

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ColIdx

impl Eq for ColIdx

impl Hash for ColIdx

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ColIdx

fn cmp(&self, other: &ColIdx) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ColIdx

fn eq(&self, other: &ColIdx) -> 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 PartialOrd for ColIdx

fn partial_cmp(&self, other: &ColIdx) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ColIdx

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
