) -> Option<BTreeSet<String>>
Expand description

The workspace sources the build actually read, from the depinfo rustc writes beside every artifact (<artifact>.d: a make rule whose prerequisites are every file that went into it). None when no depinfo could be read, which means “do not prune”.

Source discovery follows mod declarations because that is what rustc RESOLVES; this is what it COMPILES. A module behind a #[cfg] that is off is resolved and never built, and its obligations can never be covered – smallvec’s serde, borsh, rayon and specialization modules are 142 such lines. Reading the build is exact for every cfg predicate, where evaluating them here would have to reproduce Cargo’s feature resolution.
