Method FindStringIndex

regex.go:360–366

FindStringIndex returns a two-element slice of integers defining the location of the leftmost match in s. The match is at s[loc[0]:loc[1]]. Returns nil if no match is found. Example: re := coregex.MustCompile(`\d+`) loc := re.FindStringIndex("age: 42") println(loc[0], loc[1]) // 5, 7

(s string)

//	loc := re.FindStringIndex("age: 42")
//	println(loc[0], loc[1]) // 5, 7
func (r *Regex) FindStringIndex(s string) []int {
	start, end, found := r.engine.FindIndices(stringToBytes(s))
	if !found {
		return nil
	}
	return []int{start, end}
}

// FindAll returns a slice of all successive matches of the pattern in b.
// If n > 0, it returns at most n matches. If n <= 0, it returns all matches.
