This source reference follows declared modules and preserves feature attributes. It includes public declarations and implementation methods in those modules. Private-module exports and trait resolution still require the compiler; not every declaration is a crate-root import. Function bodies and constant values are omitted. Source comments describe their implementation context and are not a production deployment claim.

metrics::RevocationDecisionSource

Revocation decision source (cache vs backend).

#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum RevocationDecisionSource {
    /// Decision was computed by consulting the backend (SQL/file/memory/http).
    Backend,
    /// Decision came from a positive cache entry.
    CachePositive,
    /// Decision came from a negative cache entry.
    CacheNegative,
}

Source line: 16.

metrics::RevocationDecisionSource::as_str

Convert to a stable label value.

#[must_use]
pub const fn as_str(self) -> &'static str;

Source line: 28.

metrics::RevocationDecision

One revocation check outcome (for metrics labeling).

#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum RevocationDecision {
    /// Token is revoked.
    Revoked,
    /// Token is not revoked.
    NotRevoked,
    /// Revocation status could not be determined.
    Unknown,
}

Source line: 39.

metrics::RevocationDecision::as_str

Convert to a stable label value.

#[must_use]
pub const fn as_str(self) -> &'static str;

Source line: 51.

metrics::init

Initialize metrics (Prometheus scrape endpoint).

Safe to call multiple times; initialization occurs once. If the Prometheus exporter cannot be created, a fallback no-op provider is used and a warning is logged via tracing.

pub fn init();

Source line: 91.

metrics::render

Render Prometheus text format.

#[must_use]
pub fn render() -> String;

Source line: 222.

metrics::record_revocation_check

Record a revocation check.

pub fn record_revocation_check(
    backend: &'static str,
    endpoint: &'static str,
    result: &'static str,
    decision: RevocationDecision,
    source: RevocationDecisionSource,
    latency_seconds: f64,
);

Source line: 239.

metrics::record_revocation_cache_hit

Record a revocation cache hit (HTTP backend).

pub fn record_revocation_cache_hit(backend: &'static str, hit_type: &'static str);

Source line: 281.

metrics::record_secret_delivery_denied

Record a secret delivery denial.

pub fn record_secret_delivery_denied(reason: &'static str);

Source line: 295.

metrics::record_secret_request

Record a secret delivery request.

pub fn record_secret_request(result: &'static str);

Source line: 304.

metrics::record_http_request

Record an HTTP request (Google-safe labels: templated route + method + status).

pub fn record_http_request(route: &'static str, method: &'static str, status: &'static str);

Source line: 313.

metrics::record_proxy_request

Record a proxy request.

pub fn record_proxy_request(
    target_domain: &str,
    status: u16,
    result: &'static str,
    latency_ms: u64,
);

Source line: 328.

metrics::record_fingerprint_verification

Record a fingerprint verification result.

pub fn record_fingerprint_verification(result: &'static str);

Source line: 362.

metrics::record_consent_request

pub fn record_consent_request(status: &'static str);

Source line: 371.

metrics::record_dct_issued

Record a DCT issuance.

pub fn record_dct_issued();

Source line: 380.

metrics::record_destination_violation
