`rustc_mir_build::build::unpack!` macro does not appear in docs

[camelid]

The rustc_mir_build::build::unpack! macro does not appear in the online rustc API docs. I tried searching for it and also typing in different URLs.

Yet the rustc_apfloat::unpack! macro does appear in the API docs. I'm not sure why one is showing up and one is not.

Not sure if this is a rustdoc bug.

The rustc_mir_build::build::unpack! is private, rustc_apfloat one is exported. I believe we don't build our documentation with private items documented, so that'd be working as intended.

Closing, but feel free to reopen if you feel its a bug still.

Ah, I was wondering if that could be it, but I missed the #[macro_export] since rustdoc scrolls so the top of the page is the top of the declaration, not the attributes.

Hmm, that's weird: other items that are private show up in the documentation. Do non-exported macro_rules! not count as ordinary "private items"?

[camelid]

E.g. rustc_mir_build::build::mir_build, which is private.

Actually it looks we do document private items for the compiler:

rust/src/bootstrap/doc.rs

Lines 525 to 530 in 44ae0b8

	// Build cargo command.
	let mut cargo = builder.cargo(compiler, Mode::Rustc, SourceType::InTree, target, "doc");
	cargo.rustdocflag("--document-private-items");
	cargo.rustdocflag("--enable-index-page");
	cargo.rustdocflag("-Zunstable-options");
	compile::rustc_cargo(builder, &mut cargo, target);

This occurs in non-compiler code too, so I opened a rustdoc issue: #78091.
