Struct EvalContext 

pub struct EvalContext<'a> {
    pub seen_before: Option<&'a dyn Fn(&str) -> bool>,
}

Caller-supplied runtime context for evaluate_plan.

Evaluation stays synchronous and I/O-free: instead of the engine touching storage, callers hand in an optional seen_before predicate that decides whether an automated reply was already sent to a sender within its respond period.

Fields

seen_before: Option<&'a dyn Fn(&str) -> bool>

Respond-once hook for the vacation action (RFC 5230): return true when a reply was already sent to this sender within the configured period. When None, no dedup is applied and the outcome always carries the reply (hosts can dedup themselves using the to/days fields of VacationReply, or use the ready-made VacationTracker).

Implementations

impl<'a> EvalContext<'a>

pub fn with_seen_before(self, seen_before: &'a dyn Fn(&str) -> bool) -> Self

Attach a respond-once dedup predicate.

Trait Implementations

impl<'a> Default for EvalContext<'a>

fn default() -> EvalContext<'a>

Returns the “default value” for a type.
