Perhaps this could just be:
enum Maybe<T> {
Real(T),
Empty,
}
impl<W: Write> Write for Maybe<W> { ... }
impl<R: Read> Read for Maybe<W> { ... }

Thanks @sfackler! A few notes:

I think this needs a surrounding Ok (above as well), perhaps jut a get(...).map(|handle| ...) ?

Just a few minor nits, but otherwise r=me, thanks @sfackler! |

STD_OUTPUT_HANDLEisn't aHANDLEso you need toGetStdHandleto get the actualHANDLEtoCloseHandle.- Write a separate test which does
SetStdHandle(STD_OUTPUT_HANDLE, NULL)so it can testprintln!'s ability to replace stdout with a sink, rather than just stdout's ability to ignore errors.

Closes rust-lang#25977 The various `stdfoo_raw` methods in std::io now return `io::Result`s, since they may not exist on Windows. They will always return `Ok` on Unix-like platforms. [breaking-change]

I tagged this as stable-regression since it changes the behavior of stdio. |
