This is a "proxy" toolchain for using of a remote installation of Rust/Cargo etc. from the "light" local PC installation.
- Start as in the manual:
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain none -y
- copy this whole project folder to the
toolchains/
folder:
$ mkdir -p ~/.rustup/toolchains ; cp -a ../rustup-toolchain-remote ~/.rustup/toolchains/
- make it default
$ rustup default rustup-toolchain-remote
- test it!
$ rustc -vV
