// build.rs for derive-deftly-macros
// We recompile some of our macro code in tests, with cargo
// features that aren't declared in the package's Cargo.toml.
// And, we have a nonstandard RUSTFLAGS --cfg=derive_deftly_dprint
// for debugging output.
//
// Here, we tell rustc, via cargo, that these are all allowed.
//
// Another effect is that this build.rs file
// causes OUT_DIR to be available in `check.rs`.
// This is a subset of tests/build.rs, written to be as minimal
// (and fast to compile) as possible.
fn main() {
// We must use deprecated single colon `cargo:rustc...` syntax,
// because otherwise cargo thinks we're violating our MSRV.
// https://github.com/rust-lang/cargo/issues/14147
