constraints

Overview ¶

Package constraints provides type constraints for generic programming.

This package defines numeric type constraints used throughout the gust library for generic type parameters, including PureInteger, Integer, and Digit constraints.

Package constraints provides type constraints for generic programming.

This package defines type constraints used throughout the gust library for generic type parameters, including ordering, numeric, and comparison constraints.

Examples ¶

// Use Ordering for comparisons
ord := constraints.Compare(1, 2)
if ord.IsLess() {
	fmt.Println("1 is less than 2")
}

// Use constraints in generic functions
func max[T constraints.Ord](a, b T) T {
	if constraints.Compare(a, b).IsGreater() {
		return a
	}
	return b
}

// Use numeric constraints
func sum[T constraints.Digit](values []T) T {
	var total T
	for _, v := range values {
		total += v
	}
	return total
}
