Description
I am looking for a command to tell me whether a toolchain would have to be downloaded/installed without actually downloading or installing anything.
Hypothetically:
$ rustup <args>
# exit code 0 => no installation necessary
# exit code 1 => installation necessary
Does such a command exist today?
Please note that I am aware of this issue and PR:
- Tracking: Rustup should not perform implicit installations #3635
- feat(cli)!: remove implicit toolchain installation #3985
If I understand correctly, the latter suggests that such a command may be available soon.
