is there a way to disable seeing warnings if there are errors blocking compilation?

[alok]

most of the time, if i have compile error(s), i want to see only that error. warnings take up my attention needlessly.

could this be a command line flag or an option to how error format is set now?

@alok it seems using RUSTFLAGS=-Awarnings with cargo build hides warnings. Not conditionally, and it leads to recompile it seems, but maybe that's enough for you.

You could also use cargo rustc -- -Awarnings which doesn't recompile, but can only build one crate.

i’m actually looking for the conditional behavior since it automates a common workflow: first make it work (no errors), then make it work well (no warnings).

RUSTFLAGS=-Awarnings flag works for me removing all the warnings. I am most interested on errors rather than warnings. When you provide this a flag, all cranes are re-complied.

Whether or not warnings are printed should have nothing to do with whether you need to recompile smh

You don't think that you might end up missing out on warning messages that actually explain the circumstances that lead to the error? Say, a warning on a likely-problematic declaration and an error on the attempt to use whatever was declared?

Closing this as i'm not sure there's much to be done here in a way that doesn't have concerns and there are alternatives present as listed above.
