This seems like a good idea to me, so thanks @rapha! This does, however, probably force our hand in having this new functionality be insta-#[stable]. I'm personally OK with that, however.

Could you change the imports of core::iter::IntoIterator to just iter::IntoIterator as well?

[rapha]

Thanks. I added doc and stability annotations to match those on the Iter type, adding that it was an "owning" iterator.

[rapha]

Do you need me to do anything more on this?

[alexcrichton]

Ah thanks for the reminder @rapha! I intended on just running this by some others to get their opinion as well. I believe now this is good to go! In the meantime, however, we've bumped the version number, so could you update the since tag here to 1.1.0 instead of 1.0.0? After that I'll r+

[bluss]

Shouldn't it have another IntoIterator impl to match the fn iter(&self) method too?

[alexcrichton]

@bluss in theory, yes, but it's not necessarily required one way or another as it's backwards compatible to add. @rapha would you be interested in adding this, however?

@rapha ah I forgot this part, but you'll also need to choose a unique feature name for this as the same feature name can't have multiple versions it became stable in (e.g. the rust1 feature here was stable as of 1.0.0, not 1.1.0

[rapha]

@bluss Is this the implementation of IntoIterator for &Receiver what you had in mind?

[alexcrichton]

Ah sorry by new feature name I meant more something along the lines of receiver_into_iter or something like that

[alexcrichton]

@rapha looks good to me! Could you also squash the commits together?

[rapha]

Done

[alexcrichton]

One last instance of rust1_1

[bluss]

Yes that's great. It's consistent now that the .iter() method has a corresponding IntoIterator impl, thank you!
