1. Use strings.TrimPrefix instead of fmt.Sscanf and simplify the code. 2. Add a test case and a benchmark. The benchmark shows some improvement, compared to the old implementation: name old time/op new time/op delta FindDeviceGroup-4 39.7µs ± 2% 26.8µs ± 2% -32.63% (p=0.008 n=5+5) name old alloc/op new alloc/op delta FindDeviceGroup-4 6.08kB ± 0% 4.23kB ± 0% -30.39% (p=0.008 n=5+5) name old allocs/op new allocs/op delta FindDeviceGroup-4 117 ± 0% 6 ± 0% -94.87% (p=0.008 n=5+5) Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
