IncrementalMemo

Struct IncrementalMemo 

Source
pub struct IncrementalMemo {
    pub last_eval_count: u64,
    pub last_memo_hits: u64,
    /* private fields */
}
Expand description

Memo store for incremental evaluation (C-055, spec/performance.md §2): fingerprint → evaluated value plus the diagnostics produced while evaluating it. Reused across evaluate_incremental calls. Telemetry (last_*) refreshes every call. The store is bounded (see the cap in evaluate_incremental): clearing it only loses hits, never correctness.

Deliberately NOT derive(Debug): the store holds evaluated values (including plaintext intermediates), and a derived dump would print document content into any log that formats the memo. The manual impl below reports shape only — entry count and telemetry. Secret-kind values additionally carry Value’s own redacting Debug wherever else they are formatted.
