stringset
http://godoc.org/bitbucket.org/creachadair/stringset
The stringset package implements a lightweight set-of-strings type based
around Go's built-in map type.
Generating the Code
The stringset package is generated by the makeset program from source
templates core.go.in (the main package source) and core_test.go.in (for the
unit tests). If you need to modify the templates, edit those files and run:
go generate ./makeset
to update the static.go file. You can then re-generate the stringset
package by running:
go run ./makeset -config makeset/stringset.toml -output .
