| # disable incremental compilation. | |
| # | |
| # incremental compilation is useful as part of an edit-build-test-edit cycle, | |
| # as it lets the compiler avoid recompiling code that hasn't changed. however, | |
| # on CI, we're not making small edits; we're almost always building the entire | |
| # project from scratch. thus, incremental compilation on CI actually | |
| # introduces *additional* overhead to support making future builds | |
| # faster...but no future builds will ever occur in any given CI environment. | |
| # | |
| # see https://matklad.github.io/2021/09/04/fast-rust-builds.html#ci-workflow | |
