Implement read_buf for a few more types #108326

tmiasko · 2023-02-21T22:17:53Z

Implement read_buf for TcpStream, Stdin, StdinLock, ChildStdout,
ChildStderr (and internally for AnonPipe, Handle, Socket), so
that it skips buffer initialization.

The other provided methods like read_to_string and read_to_end are
implemented in terms of read_buf and so benefit from the optimization
as well.

This commit also implements read_vectored and is_read_vectored where
applicable.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

Stabilizing library features
Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
Changing public documentation in ways that create new stability guarantees
Changing observable runtime behavior of library APIs

thomcc · 2023-02-22T00:15:16Z

Does this change stable API? It probably should have an ACP regardless...

tmiasko · 2023-02-22T00:26:10Z

There are no changes in public API. It only optimizes the implementation of read_buf (the provided implementation initializes the buffer completely and delegates to read).

thomcc · 2023-02-22T00:27:22Z

Oh right, of course. Sorry, I'll take a look later.

thomcc · 2023-02-26T19:39:56Z

Yeah these seem fine. I don't think it's worth blocking rollup since I doubt these types are used much in the compiler.
