This isn't async, since it needs to finish to return a value with which global RLSConfiguration is created.
For the same reason it only parses the result and it's not a complete function that uses CONFIGURATION.rustupPath value, since it's called during CONFIGURATION construction.
As a side note, the configuration probably will need to be redesigned later on, as currently it's a global that's lazily constructed once and doesn't handle 'rust-client.*' value changes

Could you add the 'side note' as a FIXME or file an issue please?

I think this whole function should live in rustup.ts, rather than here.

Done! Sorry it took so long, I forgot about it 😞 Can't think of a way to reliably test it (especially detecting local overrides) apart from using docker or a separate bash script that sets default toolchain to different one and tests the function output somehow with each change. |

Thanks! |
Fixes #179.
This allows the
'rust-client.channel'option to benulland if so, the extension tries to infer the active channel from runningrustup showin current workspace directory.Manually tested with alternating stable/nightly toolchain and also with a toolchain override (servo repo), but it'd be good to also include a test for that.
