Rustup: Don't download duplicate nightly

Created on 3 Mar 2018 · 3Comments · Source: rust-lang/rustup

rustup update nightly-YYYY-MM-DD shouldn't need to update anything if the currently installed nightly is already YYYY-MM-DD. This also occurs when using a rust-toolchain file.

Yes, please don't download it again, some of us have very slow internet sometimes..

Can we install rust without rust-docs? It was useless for me, but take so much time to download & install it.

This might take some time to resolve. As far as I can tell, it would require including the date in the toolchain names and storing them with those included dates. https://github.com/rust-lang/rustup.rs/blob/master/src/rustup-dist/src/dist.rs#L254 Not sure if this is desirable behavior as this would alter something like rustup default nightly to something like rustup default nightly-2019-02-05. Hopefully one of the primary contributors will respond and correct me.
