Enum DepGraphLoadOutcome 

pub enum DepGraphLoadOutcome {
    Loaded {
        graph: DepGraph,
    },
    Missing,
    VersionMismatch {
        file_version: u32,
        expected_version: u32,
    },
    Corrupt {
        message: String,
    },
    IoError {
        message: String,
    },
}

Outcome of attempting to load the persisted depgraph from a cache directory.

Returned by classify_load so the daemon can both seed its in-memory graph and surface the load result to operators (stderr + last-session.log). The variants mirror the failure modes the daemon must handle distinctly:

• Loaded — file present, magic + version + payload all valid; the graph is ready to serve hits from the very first lookup.
• Missing — no depgraph.bin in the cache dir. Genuine cold start.
• VersionMismatch — file present but the embedded version tag does not match this build. The on-disk format changed since the prior session.
• Corrupt — magic mismatch, truncated, or payload validation failed.
• IoError — any other I/O failure reading the file.

Implementations

impl DepGraphLoadOutcome

pub fn into_graph(self) -> Option<DepGraph>

Returns the loaded graph if this outcome is Loaded, else None.

pub fn warning(&self, path: &Path) -> Option<String>

Returns a human-readable warning message for non-Loaded, non-Missing outcomes. Used by the daemon to emit a clear notice on stderr AND in the per-session log so operators can see exactly why the warm-load failed and the session fell back to cold behavior.

Trait Implementations

impl Debug for DepGraphLoadOutcome

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
