Allow rustup and rust-init to install package from local file?

[canfoderiskii]

I've been faced with some network problem and the direct download speed is very slow and a time-out error can be easily seen.
But I can use other downloading tools like "Internet Download Manager" to successfully fetch file from the link like this "https://static.rust-lang.org/dist/2016-12-21/rustc-1.14.0-x86_64-pc-windows-gnu.tar.gz".

I can see that when rustup or rust-init start downloading, it always creates a temp file in $HOME/.rustup/tmp.

Is there any way to tell the rustup or rust-init not to create a new tmp file but use the .tar.gz file I just downloaded via other method?
Is there any command line parameters for this feature? or is it possible to be added?

You can decompress the archive to wherever and use the method cited above to link it into rustup. It just won't be recognized as from release channel.

@louy2 Thank you.

1. But how can I specify the location of rust-std package? I also downloaded the rust-std-1.14.0-x86_64-pc-windows-gnu.tar.gz seperately.
2. How to add the source code of rust in this way?

Oh, I just noticed that you only downloaded rustc.

I downloaded my archive here: https://www.rust-lang.org/en-US/other-installers.html

It comes with rustc, cargo, rust-doc, rust-std, etc.

You can also download source code at the above mentioned link.

@louy2 Thank you, I think the offline archive is best for me.
