`#[inline]` integer parsing functions This improves the performance of `str::parse` into integers. Before: ``` compare fastest │ slowest │ median │ mean │ samples │ iters ╰─ std │ │ │ │ │ ├─ 328920585 10.23 ns │ 24.8 ns │ 10.34 ns │ 10.48 ns │ 100 │ 25600 ├─ 3255 8.551 ns │ 8.59 ns │ 8.551 ns │ 8.56 ns │ 100 │ 25600 ╰─ 5 7.847 ns │ 7.887 ns │ 7.847 ns │ 7.853 ns │ 100 │ 25600 ``` After: ``` compare fastest │ slowest │ median │ mean │ samples │ iters ╰─ std │ │ │ │ │ ├─ 328920585 8.316 ns │ 23.7 ns │ 8.355 ns │ 8.491 ns │ 100 │ 25600 ├─ 3255 4.566 ns │ 4.588 ns │ 4.586 ns │ 4.576 ns │ 100 │ 51200 ╰─ 5 2.877 ns │ 3.697 ns │ 2.896 ns │ 2.945 ns │ 100 │ 102400 ``` Benchmark: ```rust fn std(input: &str) -> Result<u64, ParseIntError> { input.parse() } ``` |
