Add io::Write::write_all_vectored by Thomasdezeeuw · Pull Request #70612 · rust-lang/rust

Thomasdezeeuw · 2020-03-31T13:18:35Z

Similar to io::Write::write_all but uses io::Write::write_vectored
instead.

I went with the original implementation I suggested, just to get some experience with it. I was thinking that maybe we could always set bufs to an empty array, even in case of an error, as is already the case if everything gets written.

Centril · 2020-03-31T13:29:41Z

@Thomasdezeeuw Can you split the module after this PR? It's getting close to the 3000 LOC threshold.

Thomasdezeeuw · 2020-03-31T14:00:07Z

@Centril Sure, anything you suggest that should move to its own file? Or should I start with moving the tests?

Also I only ran libcore tests locally, so I'll fix the pr and push :)

Centril · 2020-03-31T14:30:14Z

@Thomasdezeeuw Some themes to consider:

Move out the traits vs. data types
Separate Read from Write
IoSlice (and vectored stuff) in its own module

A few inline comments, mostly documentation though.

Regarding the discussion in #70436: I am also not very happy about an API like this. Especially since we recommend in the docs to "treat it as if bufs was consumed by this method". Feels wrong to me, as in Rust, we should be able to assert this on a type level somehow. But maybe it's not that bad, as this is mainly a fairly low level API anyway. And unfortunately, I don't have a great idea how to use the type system to make this better.

I personally don't like the idea of making this method implementation more complicated or slower to get around this API quirk. So I'm not quite sure what to do about this...

Also adds some more tests with different length IoSlices.

@LukasKalbertodt I've address all comments, except for the tracking issue one.

One tiny thing still!

LukasKalbertodt · 2020-04-06T22:13:56Z

Thanks!

As I said, I don't particularly like the API. But let's get it landed, it's unstable after all. We can still change and discuss the exact API later.
