This is a tracking issue for the ACP rust-lang/libs-team#375 .
The feature gate for the issue is #![feature(anonymous_pipe)].

Steps

• Implement the ACP Initial implementation of anonymous_pipe API #127153
• Enable std::io::copy specialisation Enable std::io::copy specialisation for std::pipe::{PipeReader, PipeWriter} #128303
• Adjust documentation (see instructions on rustc-dev-guide)
• Formatting for new syntax has been added to the Style Guide (nightly-style-procedure)
• Stabilization PR (see instructions on rustc-dev-guide)

Implementation history

You might want to fix the typo in the title and feature name - it's an anonymous pipe, not an annoymous pipe.

Thanks!

I've fixed the typo in this issue and the linked PR.

I think we can now add specialisation to std::io::copy for std::pipe

I'm thinking about a new method for checked conversion from OwnedFd on unix.

I think it would be quite helpful for jobserver-rs

Currently the documentation for this module is very bare-bones, quite far from the depth and quality we are used to in other parts of the standard library. There's not even a single example. This should be resolved before stabilization.
