This can be moved to Cargo.toml, right?

Yep, I am happy to implement it there if preferred.

OK, now it's in Cargo.toml's [lints.rust].
It would be handy to have async wrappers for the pipe types (from std::io::pipe()), so impl IoSafe for both. The pipe types were introduced in 1.87, but the MSRV for async-io appears to be 1.63 currently. So, protect the impls with cfg()s and use autocfg to detect the type availbility, similar to what was done in a20076f ("Implement I/O-safe traits (smol-rs#84)") Signed-off-by: Jeremy Kerr <jk@codeconstruct.com.au>

The pipe types were introduced in 1.87, but the MSRV for async-io appears to be 1.63 currently. So, protect the impls with a cfg(has_pipe), and use autocfg to set has_pipe, like was done in a20076f ("Implement I/O-safe traits (#84)")
