[src] links point to other website

The [src] links on https://docs.rs/futures-preview/0.3.0-alpha.12/futures/stream/struct.Forward.html point to https://rust-lang-nursery.github.io/futures-api-docs/0.3.0-alpha.12/futures_util/src/futures_util/stream/forward.rs.html#22-26. This seems likely to be related to the #[doc(html_root_url)] setting in the sub-crate that this type is actually from.

This is entirely because of the html_root_url attribute, though it should be overridden by a --extern-html-root-url path that docs.rs is passing to rustdoc. Since the build log shows that that flag is being passed, i'm going to assume this is an upstream rustdoc problem. I'll try transferring the issue to rust-lang/rust, since that's where rustdoc lives.

[QuietMisdreavus]

Apparently you need full admin access to use the "Transfer issue" button, so i've just reopened the issue over there as rust-lang/rust#58472. I'll close the issue here since the work all needs to happen upstream.

[QuietMisdreavus]

Looks like i was mistaken - it's not a bug in upstream rustdoc, but in docs.rs here. To quote @ollie27 in the rust-lang/rust issue:

The build log shows rustdoc was passed --extern-html-root-url 'futures_util_preview=https://docs.rs/futures-util-preview/0.3.0-alpha.12' but the crate name is futures_util not futures_util_preview. It looks like docs.rs needs to use the actual crate name not the package name.

This may be fixed by rust-lang/rust#67804.

This was fixed by #1188 (and looking at that PR, looks like this is a duplicate of #1166).
