slice impl for [T; i] is repeated too much in rustdoc

[mdinger]

The slice page is huge. These [T; N] really need to be condensed at least in rustdoc somehow. This is absurd.

impl<T> Clone for [T; 0] where T: Copy
...
impl<S, T> Hash<S> for [T; 0] where S: Hasher, S: Writer, T: Hash<S>
...
Repeats for 0...31 along with all the sub-functionality each `impl` brings
...
impl<T> Clone for [T; 32] where T: Copy
...
impl<S, T> Hash<S> for [T; 32] where S: Hasher, S: Writer, T: Hash<S>

#[doc(hidden)] for every impl but one and put a note on that one?

[mdinger]

Sounds good to me. 70% of that page is that type.

It seems like rustdoc could just treat all [T; ...] as the same, by default (providing e.g. mouse-over text or a [+] button to give the exact lengths that are implemented).

pssssh, we're fine

@steveklabnik it's... beautiful

[tomjakubowski]

I think @lifthrasiir's suggestion is a good workaround for the standard docs but rustdoc could certainly stand to improve in this area.

I don't forsee this getting fixed in rustdoc. Once we get type level integers, this will just go away, and until then, it's a bit gross, but other languages have basically the same issue.

It seems like I might be alone here, so I'll leave this open, but I'm really tempted to just close as WONTFIX.

Triage: no comments in a year. I feel the same as I did then; this isn't really a rustdoc-level thing to fix.
