docs: dead link to std::vec::Vec::extend()

[matthiaskrgr]

extend_from_slice links to extend however it seems there is no such method in the docs.

[matthiaskrgr]

Ok that is interesting, when I click the link from within the doc, nothing happens, however if I click the link from this issue, I get scrolled to impls. 😕

I'm using firefox 61.0.1

It's because the method extend is within the Extend trait implementation. Since it's not really an issue, I wonder if we should close it now...

cc @rust-lang/docs

The link is broken in the docs, so I think we should leave this open since we need to fix that.

[GuillaumeGomez]

No it's not really broken since the link exists: https://doc.rust-lang.org/stable/std/vec/struct.Vec.html#impl-Extend%3CT%3E

The real issue here is that the block doesn't get expanded when you click on the link.

Fair enough. If there's an issue already open for that, I'd be in favor of closing this issue in favor of the other one

[GuillaumeGomez]

I suppose #52517 is the one?

Noticed another error in the docs of extend_from_slice:

Note that this function is same as extend except that it is specialized to work with slices instead. If and when Rust gets specialization this function will likely be deprecated (but still available).

extend is already specialized for slices

[GuillaumeGomez]

@bjorn3 Please open an issue for this one, otherwise it'll get lost.

[bjorn3]

Sure

#52517 is similar but we need to have the same code for hashchange to address the issue.
