	# 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
	# for details.
	CARGO_INCREMENTAL: 0
	# Allow more retries for network requests in cargo (downloading crates) and
	# rustup (installing toolchains). This should help to reduce flaky CI failures
	# from transient network timeouts or other issues.
	CARGO_NET_RETRY: 10
	RUSTUP_MAX_RETRIES: 10
	# Don't emit giant backtraces in the CI logs.
