Struct GraphCacheFile 

pub struct GraphCacheFile {
    pub key: StableFileKey,
    pub file_id: FileId,
    pub content_hash: u64,
}

Source freshness for one file in a graph-cache manifest.

Fields

key: StableFileKey

Persistable identity for the file.

file_id: FileId

Current in-memory identifier for the file.

The stable key is the durable identity, but the persisted ModuleGraph is still FileId-keyed. Until a future graph-cache format remaps graph edges through stable keys, a changed assignment must miss rather than trust a graph whose modules[file_id] indexes point at different files.

content_hash: u64

xxh3 hash of the parsed source content.

Content, not (mtime, size): the metadata pair is writer-controlled and a same-length rewrite with a restored mtime leaves it unchanged, so a metadata-keyed manifest can hand back the previous run’s graph for a tree that no longer matches it. The hash is free here because the parse stage already computed it, and unlike a ctime it survives cp -Rp and CI cache restores, which is what makes a warm graph reusable across checkouts at all.

0 when the run produced no module for the file (an unreadable source).
