Clarify in which component and/or profile rustdoc is

[ojeda]

Describe the problem you are trying to solve
It is not clear from https://github.com/rust-lang/rustup/blob/master/doc/src/concepts/components.md from which component rustdoc comes from, and therefore it is not clear that it is included in the minimal profile.

Describe the solution you'd like
Clarify in https://github.com/rust-lang/rustup/blob/master/doc/src/concepts/components.md from which component rustdoc comes from.

Perhaps also clarify in https://github.com/rust-lang/rustup/blob/master/doc/src/concepts/profiles.md that the components in the minimal profile also include other tools.

rustdoc is in the rustc component. You cannot install rustc without also installing rustdoc.

[ojeda]

Yeah, exactly: that is not clear from the docs. It just says "rustc — The Rust compiler.", without mentioning rustdoc.

closing in favour of that PR

[ojeda]

Hmm... an issue should not be closed until the PR is merged (and if referenced, GitHub will close it for you).

[rbtcollins]

for some reason I thought this came from the channels and thus was in the wrong repository, sorry.

[ojeda]

No problem at all :D
