SassFunctionError

Swift
public enum SassFunctionError: Error, CustomStringConvertible

Errors thrown for common SassFunction scenarios.

Generally these are thrown from your SassFunctions by SassValue family methods in response to error scenarios, for example a user passes a number where you expect a string, or a number in radians where you expected a length. Then the compilation fails, giving the description of the error as the failure reason.
