I'm not sure if I should create this issue in rustup repo or in rust.
Problem
When you install any musl toolchain, e. g. x86_64-unknown-linux-musl, rust-docs component doesn't install.
I've digged into the issue, and found out that for some reason rust-docs is missing for some triples, among them are *-musl ones. https://static.rust-lang.org/dist/channel-rust-stable.toml

Steps

  1. rustup toolchain install stable-x86_64-unknown-linux-musl
  2. rustup doc

Possible Solution(s)
Add tarballs for *-musl triples to the server.

Notes

Output of rustup --version:

rustup 1.22.1 (2020-07-28)

Output of rustup show:

Default host: x86_64-unknown-linux-musl
rustup home:  /home/artur/.rustup

stable-x86_64-unknown-linux-musl (default)
rustc 1.46.0 (04488afe3 2020-08-24)

    The docs are not available for non-tier1 platforms due to the overhead and CI time involved in building them. This issue is tracked in rust-lang/rust#69525. It may be possible for the channel manifests to redirect most platforms to the linux docs (probably x86_64-unknown-linux-gnu). As a workaround, you can download the docs from x86_64-unknown-linux-gnu.

    Oh, BTW, the x86_64-unknown-linux-musl includes the rust-docs component in the beta channel (via rust-lang/rust#74871) which should hit stable next week.

    Given Eric's response above, I'm going to close this issue. Hopefully everyone is happy now.
