vec::u3::is_ascii in auto-gen'd v0.3 docs, not in language

[Havvy]

http://dl.rust-lang.org/doc/0.3/core/vec_u8.html#function-is_ascii

There's a function here, seemingly malformed (takes a T, but is not a generic function), but more importantly, is not a part of Rust 0.3.

You're right, is_ascii was removed from vec well before the 0.3 release. I'm not sure why the library docs on the web site for 0.3 are so out of date. @graydon ?

[graydon]

it was never in core::vec::u8. This is a rustdoc bug, I think; the giveaway is that the code uses the module-local type parameter T, which is from the uint-templatized code over in core::u8. Where it still exists.

[pnkfelix]

I infer from the comments that the 0.3 docs are periodically re-generated via a current rustdoc, and thus this bug will go away when rustdoc is fixed.

Not critical for 0.6; de-milestoning

No longer relevant, can be closed.

[pnkfelix]

Indeed. I am no longer confident that my earlier assertion (from comment above) that the docs are re-generated is correct; but in any case, without a more concrete illustration of a direct bug in rust doc, it is hard to take action on this. Closing.
