   Thank you @alamb for review, addressed the comments now.
   
   And also the benchmark result for utf8view seems better:
   
   
   ```rust
   small_bench_primitive   time:   [6.2293 µs 6.2540 µs 6.2810 µs]
                           change: [+0.6034% +1.1278% +1.6922%] (p = 0.00 < 
0.05)
                           Change within noise threshold.
   Found 11 outliers among 100 measurements (11.00%)
     1 (1.00%) low mild
     7 (7.00%) high mild
     3 (3.00%) high severe
   ```
   
   ```rust
   small_bench_primitive_with_utf8view
                           time:   [6.0220 µs 6.0420 µs 6.0649 µs]
   Found 3 outliers among 100 measurements (3.00%)
     1 (1.00%) low mild
