Functions

func CloseAll

func CloseAll(closers ...io.Closer) error

CloseAll calls Close() on every closer, returning the err from the first one that returns a non-nil error.

func Git

func Git(arg ...string) (string, error)

func Must

func Must(err error)

Must panics if err is non-nil

func PropagateCloseError

func PropagateCloseError(closer io.Closer, f func() error) (err error)

PropagateCloseError calls f then calls closer.Close(), returning the error from Close() if f did not return an error. Errors from Close() when writing can return important errors that should not be thrown away.

func StringSliceContains

func StringSliceContains(s []string, t string) bool

Types

type StringSet

type StringSet struct {
	// contains filtered or unexported fields
}

func NewStringSet

func NewStringSet() *StringSet

func NewStringSetWithValues

func NewStringSetWithValues(values []string) *StringSet

func (*StringSet) Add

func (ss *StringSet) Add(s string) bool

Adds s to the set and returns true if the string wasn't already present

func (*StringSet) AddAll

func (ss *StringSet) AddAll(values ...string) *StringSet

func (*StringSet) Contains

func (ss *StringSet) Contains(s string) bool

func (*StringSet) Values

func (ss *StringSet) Values() []string
