// bun_windows_sys is a #![no_std] leaf crate that several workspace crates
|
||
|
|
// (bun_errno, bun_spawn_sys) depend on unconditionally so that Win32 POD types
|
||
|
|
// like IO_COUNTERS resolve on every target. Its #[link(name = "...")]
|
||
|
|
// attributes must therefore be gated behind cfg(windows), or the linker for
|
||
|
|
// any standalone test binary on a non-Windows host sees
|
||
|
|
// ld.lld: error: unable to find library -lntdll / -lkernel32 / ...
|
||
|
|
// as soon as bun_windows_sys.rlib lands on the link line.
|
||
|
|
//
|
||
|
|
// `cargo check --tests` type-checks only and will not catch this; it has to
|
||
|
|
// be `cargo test --no-run` so rustc actually drives the linker. The crate has
|
||
|
|
// zero dependencies, so linking completes in well under a second on a warm tree.
