Before

test uri_parse_relative_medium ... bench:         128 ns/iter (+/- 12) = 468 MB/s
test uri_parse_relative_query  ... bench:         169 ns/iter (+/- 15) = 497 MB/s
test uri_parse_slash           ... bench:          32 ns/iter (+/- 0) = 31 MB/s
test uri_parse_full_query      missing, not supported

After

test uri_parse_relative_medium ... bench:         153 ns/iter (+/- 4) = 392 MB/s
test uri_parse_relative_query  ... bench:         174 ns/iter (+/- 1) = 482 MB/s
test uri_parse_slash           ... bench:          28 ns/iter (+/- 0) = 35 MB/s
test uri_parse_full_query      ... bench:         293 ns/iter (+/- 15) = 293 MB/s
