Enum NonFiniteLocation 

#[non_exhaustive]
pub enum NonFiniteLocation {
    #[non_exhaustive]
    MatrixCell {
        row: usize,
        col: usize,
    },
    #[non_exhaustive]
    VectorEntry {

    },
    #[non_exhaustive]
    Step {
        index: usize,
    },
    Scalar,
}

Location at which a non-finite value was observed.

Examples

use la_stack::prelude::*;

match LaError::non_finite_input_matrix(1, 2) {
    LaError::NonFinite {
        location: NonFiniteLocation::MatrixCell { row, col, .. },
        ..
    } => assert_eq!((row, col), (1, 2)),
    _ => unreachable!("constructor returns a matrix-cell location"),
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

#[non_exhaustive]

MatrixCell

Cell (row, col) in matrix-shaped storage or computation.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

row: usize

Matrix row.

col: usize

Matrix column.

#[non_exhaustive]

VectorEntry

Entry in a vector input.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

index: usize

Vector index.

#[non_exhaustive]

Step

Indexed step in a factorization, solve, or reduction.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

index: usize

Step index.

Scalar

Scalar value without a meaningful matrix or vector coordinate.
