Struct DedupSet 

pub struct DedupSet { /* private fields */ }

In-memory set of dedup keys with snapshot / restore for opt-in cross-process persistence.

Implementations

impl DedupSet

pub fn new() -> Self

Construct an empty set.

pub fn contains(&self, key: &DedupKey) -> Result<bool, PolicyError>

Returns true if key has already been recorded.

Returns PolicyError::Poisoned if a previous holder of the internal lock panicked.

pub fn insert(&self, key: DedupKey) -> Result<(), PolicyError>

Record key as seen. Idempotent.

pub fn snapshot(&self) -> Result<Vec<String>, PolicyError>

Snapshot the current set as a sorted list of hex-encoded keys, suitable for writing to a sidecar file.

pub fn extend_from_snapshot(&self, hexes: &[String]) -> Result<(), PolicyError>

Replay a snapshot produced by Self::snapshot back into this set. Malformed entries are skipped with a tracing::warn!.
