Struct ValidationCache 

pub struct ValidationCache { /* private fields */ }

The disk-backed pattern-validation cache.

Implementations

impl ValidationCache

pub fn load(path: &Path) -> Self

Load (or start) the cache at path: a missing file starts empty (LoadOutcome::Absent), a corrupt or unreadable file starts empty (LoadOutcome::Corrupt), and entries stamped with another engine version drop on load.

pub fn outcome(&self) -> &LoadOutcome

The load outcome (the caller logs it).

pub fn key(pattern: &str, ignore_case: bool) -> String

The reference _key: sha256 over the pattern, a 0x00 separator, and the flags char (i when case-insensitive).

pub fn get(&self, pattern: &str, ignore_case: bool) -> Option<(bool, String)>

The cached verdict, None when the pattern was never certified.

pub fn put(&self, pattern: &str, ignore_case: bool, safe: bool, reason: &str)

Record one verdict and persist atomically (tmp file plus rename; a failed write leaves the in-memory entry and drops the persistence, the reference’s logged-but-survivable outcome).

pub fn validate_compat(&self, pattern: &str) -> (bool, String)

The cached validation entry point (the validate_pattern_safety compat shape): the cheap deterministic layers always re-run, the empirical cost-verdict layer answers from the cache on a hit and persists on a miss.

pub fn validate_with_flags( &self, pattern: &str, ignore_case: bool, ) -> (bool, String)

ValidationCache::validate_compat with the flags char explicit (a pattern validated under different flags caches separately).

Trait Implementations

impl Debug for ValidationCache

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

Formats the value using the given formatter.
