Struct VacationTracker 

pub struct VacationTracker { /* private fields */ }

In-memory ledger for vacation respond-once-per-sender-per-period semantics (RFC 5230). Record a reply when one is sent; query with seen_before to decide whether another is due. Thread-safe; usable directly as an EvalContext::seen_before predicate.

use sieve_kit::actions::VacationTracker;

let tracker = VacationTracker::new();
assert!(!tracker.seen_before("alice@example.com", 7));
tracker.record("alice@example.com");
assert!(tracker.seen_before("alice@example.com", 7));
assert!(!tracker.seen_before("bob@example.com", 7));

Implementations

impl VacationTracker

pub fn new() -> Self

Create an empty tracker.

pub fn seen_before(&self, sender: &str, days: u32) -> bool

Whether a reply was recorded for sender less than days days ago. Poisoned state is treated as “nothing recorded” (never panics).

pub fn record(&self, sender: &str)

Record that a reply was sent to sender, effective now.

pub fn record_at(&self, sender: &str, at: Instant)

Record a reply with an explicit timestamp — the injection point for tests and clock-control.

Trait Implementations

impl Default for VacationTracker

fn default() -> VacationTracker

Returns the “default value” for a type.
