And, necessarily, make it inhabited even on platforms without processes.

I noticed while preparing rust-lang/rfcs#3362 that there was no way for anyone to construct an ExitStatus.

This would be insta-stable so needs an FCP.

Even where actually running processes is not supported.
Needed for the next commit.

The manual trait implementations now belong on ExitStatusError,
which still can't exist.

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

Impl looks fine, but will need API review.

Ah, sorry. Now done in rust-lang/libs-team#158

The rustbot comment says (emphasis added):

Maybe that isn't quite right? I'm not sure what it should say precisely (or where to edit it).

I see that there's nothing in the PR that documents what the default is.

I think it should at least say somewhere what that default is. Having it come from a derive(Default) on a c_int feels indirect to me as well, so perhaps it would make sense to define it manually in terms of ExitCode::SUCCESS instead, say -- that would also allow putting a doc-comment on the impl.

@scottmcm

It also feels like it make make sense to make ExitCode also be Default at the same time, since it feels weird for the more-complicated type to be Default when the simple one isn't.

@ijackson

@scottmcm I generally agree with your comments.

In rust-lang/libs-team#158 @m-ou-se suggested impl From<ExitCode> for ExitStatus, which I also agree with.

In summary, I think we should

  • impl Default for ExitCode (simply SUCCESS)
  • impl From<ExitCode> for ExitStatus (with the obvious semantics, but might be worth some additional docs)
  • Document that Default for ExitStatus is "process reported successful termination", ie the result of ExitCode::success().into(), and, implement it that way.

I have put this on my personal todo list. Items 1 and 2 are insta-stable. Should I make an ACP, or can we do the FCP in the MR? It seems to me that this is all relatively uncontroversial so maybe going straight to MR is best.

I don't think any of those are ABI breaks from where this MR gets us, so this MR can go through as-is, even though it has room for improvement.

Some of the other followup work is more complicated so I'm going to do individual MRs.

impl Default for ExitCode

As suggested here
  rust-lang#106425 (comment)

Needs FCP since this is an insta-stable impl.

Ideally we would have `impl From<ExitCode> for ExitStatus` and implement the default `ExitStatus` using that.   That is sadly not so easy because of the various strange confusions about `ExitCode` (unix: exit status) vs `ExitStatus` (unix: wait status) in the not-really-unix platforms in `library//src/sys/unix/process`.  I'll try to follow that up.
