NewRegexpWrap returns a new instance of regexpWrap.

func (*RegexpWrap) FindStringSubmatch

func (re *RegexpWrap) FindStringSubmatch(_ context.Context, s string) []string

FindStringSubmatch returns a slice of strings holding the text of the leftmost match of the regular expression in s and the matches, if any, of its subexpressions, as defined by the 'Submatch' description in the package comment. A return value of nil indicates no match.

func (*RegexpWrap) MatchString

func (re *RegexpWrap) MatchString(_ context.Context, s string) bool
