Rollup merge of #80201 - saethlin:bufreader-read-exact, r=KodrAus
Add benchmark and fast path for BufReader::read_exact At work, we have a wrapper type that implements this optimization. It would be nice if the standard library were faster. Before: ``` test io::buffered::tests::bench_buffered_reader_small_reads ... bench: 7,670 ns/iter (+/- 45) ``` After: ``` test io::buffered::tests::bench_buffered_reader_small_reads ... bench: 4,457 ns/iter (+/- 41) ```
