Method FindString

regex.go:324–331

FindString returns a string holding the text of the leftmost match in s. Returns empty string if no match is found. Example: re := coregex.MustCompile(`\d+`) match := re.FindString("age: 42") println(match) // "42"

(s string)

//	match := re.FindString("age: 42")
//	println(match) // "42"
func (r *Regex) FindString(s string) string {
	b := stringToBytes(s)
	start, end, found := r.engine.FindIndices(b)
	if !found {
		return ""
	}
	return s[start:end] // Return substring of original string - no allocation for input
}

// FindIndex returns a two-element slice of integers defining the location of
// the leftmost match in b. The match is at b[loc[0]:loc[1]].
