How to handle queries outside the data domain.

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.

Nearest

Clamp to the nearest boundary value.

Linear

Linearly extrapolate using the slope at the boundary.

Polynomial(usize)

Extrapolate with a polynomial of given degree fit to the last degree+1 points.

Reflection

Mirror / reflect the index about the boundary.

Periodic

Wrap the index periodically.

Zero

Return zero outside the domain.

Constant(f64)

Return a fixed constant value outside the domain.
