Struct FailureTracker 

pub struct FailureTracker { /* private fields */ }

Per-domain, per-browser failure tracker with 10-minute TTL.

All methods are &self (no &mut self), making this safe to share across tasks via Arc<FailureTracker>.

Implementations

impl FailureTracker

pub fn new() -> Self

Create a new, empty failure tracker.

pub fn record_failure(&self, domain: &str, browser: &str)

Record a failure for a domain + browser pair (defaults to the “transient” class). See record_failure_class.

pub fn record_failure_class( &self, domain: &str, browser: &str, error_class: &str, )

Record a failure tagged with its class (“blocked”, “transient”, …) for selective clearing on stealth escalation.

pub fn record_success(&self, domain: &str, browser: &str)

Record a success – clears the failure counter for a domain + browser.

pub fn failure_count(&self, domain: &str, browser: &str) -> u32

Get failure count (0 if expired or not found).

pub fn total_failure_count(&self, domain: &str) -> u32

Get total failures across all browsers for a domain (unexpired only).

pub fn clear(&self, domain: &str)

Clear all failure records for a domain (regardless of class).

pub fn clear_class(&self, domain: &str, error_class: &str)

Clear only failures of a given class for a domain.

Used on stealth escalation: blocked failures are cleared (a higher stealth tier can bypass the block), while transient/disconnect failures are retained (escalating stealth won’t fix flaky infra, so we keep skipping a browser that keeps dropping on this domain).

pub fn cleanup(&self)

Clean up expired entries across all domains.
