Struct LIndex 

pub struct LIndex {
    pub row: usize,
    pub col: usize,
}

A single requested derivative direction in L-space: the lower-triangular entry (i, j) with i >= j. The zeroth-order “direction” (the value itself) is handled separately; this names the active first-order channels.

Fields

row: usize

Row of the lower-triangular factor entry (>= col).

col: usize

Column of the lower-triangular factor entry (<= row).

Trait Implementations

impl Clone for LIndex

fn clone(&self) -> LIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LIndex

impl Debug for LIndex

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

Formats the value using the given formatter.

impl Eq for LIndex

impl PartialEq for LIndex

fn eq(&self, other: &LIndex) -> 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.
