Implement automatically setting up a vendor dir from source * If the source root contains a Cargo.lock file it will be used to create a vendor directory * Otherwise a (descriptive) error will be thrown describing how to remediate * The caller can, of course, manually specify their own `cargoVendorDir` which will skip the default vendoring 2021-12-29 02:15:10 +03:00			`export SOURCE_DATE_EPOCH=1`

Implement compressing cargo `target` directory 2021-12-27 07:25:36 +03:00			`# See: https://reproducible-builds.org/docs/archives/`

Remove doCompressTarget option * Reducing the parameter surface area for good measure, zstd compression works pretty well and it seems redundant to support multiple ways of copying the target directory around 2021-12-31 07:25:33 +03:00			`-c "${CARGO_TARGET_DIR:-target}" \| @zstd@ -o "${target}/target.tar.zst"`

Make copyCargoTargetToOutputHook even more lazy * Instead of always installing the hook but bailing early based on the configuration, we will instead only install the hook if the configuration requests it 2021-12-29 05:53:05 +03:00			`if [ "1" = "${doCopyTargetToOutput-}" ]; then`
