pub fn build_cache_path() -> Option<PathBuf>Expand description
The build cache segment, cache/1: one container holding every payload,
expansion, and baked thumbnail a cook produced, indexed by producer and
key. A build writes this
file and no other, so a cook running against a live application never
shares a file with the segment that application writes.
Resolves against the content root rather than the writable one: a build
writes the data/ beside it, so a tree it cannot write is a tree it cannot
cook into either.
Deletable at any time; whatever is missing is recompiled.
