optimize Eq implementation for paths Filesystems generally have a tree-ish structure which means paths are more likely to share a prefix than a suffix. Absolute paths are especially prone to share long prefixes. quick benchmark consisting of a search through through a vec containing the absolute paths of all (1850) files in `compiler/`: ``` # old test path::tests::bench_path_cmp ... bench: 227,407 ns/iter (+/- 2,162) # new test path::tests::bench_path_cmp ... bench: 64,976 ns/iter (+/- 1,142) ``` |
