Struct RepeatIndex 

pub struct RepeatIndex { /* private fields */ }

Recent answers, per ref, for one session.

Implementations

impl RepeatIndex

pub fn observe(&self, ref_input: &str, code: Option<ErrorCode>)

Record what a call told its caller about ref_input: an error code, or None for a clean success (which clears the ref).

An answer with the same disposition under the same configuration keeps the FIRST time: a caller looping on a refusal must not slide the window forward. That rule is also what makes a replay’s own bookend harmless – it repeats the disposition it replayed (a Wait reports RATE_LIMITED, which is retry_after like what it waits on) – without marking requests, so a real answer arriving concurrently is never mistaken for one. A different disposition, or a success, replaces the entry.

pub fn observe_at( &self, ref_input: &str, code: Option<ErrorCode>, now: Instant, fingerprint: u64, )

RepeatIndex::observe with an explicit clock and fingerprint.

pub fn check(&self, ref_input: &str) -> Verdict

What a request for ref_input should do now.

pub fn check_at( &self, ref_input: &str, now: Instant, fingerprint: u64, ) -> Verdict

RepeatIndex::check with an explicit clock and fingerprint.
