Function containerIdxFromAddr

dgraphtest/zero_state.go:216–223

containerIdxFromAddr extracts the numeric suffix from the "zeroN" segment of a member's address and returns it as the container index used by tests.

(addr string)

// containerIdxFromAddr extracts the numeric suffix from the "zeroN" segment
// of a member's address and returns it as the container index used by tests.
func containerIdxFromAddr(addr string) (int, bool) {
	for i := range maxContainerIdxScan {
		if strings.Contains(addr, fmt.Sprintf("zero%d", i)) {
			return i, true
		}
	}
	return -1, false
}

// maxContainerIdxScan bounds the zero N scan in containerIdxFromAddr. It is
// larger than any realistic test topology.
