strset

Full-featured Go Set type for string elements.

func Example() {
	s1 := Make("red", "green", "blue", "yellow")
	s2 := MakeFromText("yellow green white")
	fmt.Println(s1.Intersection(s2))
	// Output: Set{green yellow}
}

Some features of the strset.Set type:

• Make builds a set from zero or more strings (or []string...).
• MakeFromText builds a set from a single string with elements separated by whitespace.
• String method returns elements in ascending order.
• Methods returning new sets: intersection, union, difference, symmetric difference.
• Methods updating receiver in-place for each operation above.
• Pop method to retrieve and delete one unspecified element.
• Need an immutable set? Just remove updaters.go from the build.
• 100% test coverage.
• Not thread-safe.

Happy hacking!
