Jonas Schievink a7a6f013a2 Rollup merge of #78641 - the8472:buffered-copy, r=sfackler ... Let io::copy reuse BufWriter buffers This optimization will allow users to implicitly set the buffer size for io::copy by wrapping the writer into a `BufWriter` if the default block size is insufficient, which should fix #49921 Due to min_specialization limitations this approach only works with `BufWriter` but not for `BufReader<R>` since `R` is unconstrained and thus the necessary specialization on `R: Read` is not always applicable. Once specialization becomes more powerful this optimization could be extended to look at the reader and writer side and use whichever buffer is larger.		2021-02-01 14:29:28 +01:00
