Enum NonFiniteOrigin 

#[non_exhaustive]
pub enum NonFiniteOrigin {
    Input,
    #[non_exhaustive]
    Computation {
        operation: ArithmeticOperation,
    },
}

Provenance of a non-finite value.

Examples

use la_stack::prelude::*;

let err = LaError::non_finite_computation_scalar(ArithmeticOperation::Determinant);
match err {
    LaError::NonFinite {
        origin: NonFiniteOrigin::Computation { operation, .. },
        ..
    } => assert_eq!(operation, ArithmeticOperation::Determinant),
    _ => unreachable!("constructor preserves computation provenance"),
}

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.

Input

The caller supplied a non-finite input.

#[non_exhaustive]

Computation

Finite inputs produced a non-finite arithmetic result.

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.

operation: ArithmeticOperation

Operation that produced the value.
