Is there a reasonable workflow for using rustup without having rust-docs installed?
Why not have it installed?
- From my unscientific observations, probably the longest step of using rustup to install rust (or upgrade a toolchain)
- In my CI, installation takes 40s to 2m, depending on the toolchain and host
- "large", 290 MB uncompressed
- Completely unnecessary for CIs (and for development workflows that rely on online documentation)
I looked through the source for installing rustup and the closest option I could find is --default-toolchain none but I then still need to install a toolchain without rust-docs. I tried simulating that by uninstalling rust-docs which gave me
rustup component remove rust-docs
error: component 'rust-docs' for target 'x86_64-unknown-linux-gnu' is required for toolchain 'stable-x86_64-unknown-linux-gnu' and cannot be removed
This makes me assume that the toolchain "stable" has a hard dependency on rust-docs.
