Functions

func Merge

func Merge(dst, src sets.String) sets.String

Merge merges the src sets into dst and returns dst. This assumes that dst is non-nil. For example: s1 = {a1, a2, a3} s2 = {a1, a2, a4, a5} Merge(s1, s2) = {a1, a2, a3, a4, a5} s1 = {a1, a2, a3, a4, a5}

It supersedes s1.Union(s2) when constructing a new set is not the intention.

func SymmetricDifference

func SymmetricDifference(s1, s2 sets.String) sets.String

SymmetricDifference returns the symmetric difference of two sets. For example: s1 = {a1, a2, a3} s2 = {a1, a2, a4, a5} SymmetricDifference(s1, s2) = {a3, a4, a5}

It supersedes s1.Difference(s2).Union(s2.Difference(s1)) which is a little complicated and always builds several unnecessary intermediate sets.
