Made `cargo_build_script` `streams` output group optional. #2976

Closed UebelAndre closed 2 weeks ago

UebelAndre commented 3 weeks ago

This change introduces the --@rules_rust//cargo/settings:debug_std_streams_output_group flag which can be used to enable the streams output group on cargo_build_script targets. For greater reproducibility, the flag is defaulted to false.
