These new methods allow you to ask the reader or witer up front if vectored operations are efficiently supported. Currently, you have to use some heuristics to guess by e.g. checking if the read or write only accessed the first buffer. Hyper is one concrete example of a library that has to do this dynamically: https://github.com/hyperium/hyper/blob/0eaf304644a396895a4ce1f0146e596640bb666a/src/proto/h1/io.rs#L582-L594 2019-11-30T02:43:27+00:00 David Tolnay dtolnay@gmail.com 2019-11-27T18:29:00+00:00 urn:sha1:4436c9d35498e7ae3da261f6141d6d73b915e1e8 This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libstd. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference 2019-04-27T16:19:34+00:00 Steven Fackler sfackler@gmail.com 2019-04-27T16:19:34+00:00 urn:sha1:89ff7cde5a81e1e1022498d24a03c816b79d9d68 2019-04-27T15:34:08+00:00 Steven Fackler sfackler@gmail.com 2019-04-27T15:34:08+00:00 urn:sha1:bd177f3ea31e47b94dd400239a9badfe2bd47355 This renames `std::io::IoVec` to `std::io::IoSlice` and `std::io::IoVecMut` to `std::io::IoSliceMut`, and stabilizes `std::io::IoSlice`, `std::io::IoSliceMut`, `std::io::Read::read_vectored`, and `std::io::Write::write_vectored`.
