acme-proxy-admin 0.6.1

//! `/api/audit` — the CA's audit trail, read-only.
//!
//! There is no mutating route in this file and there is not meant to be one.
//! The trail is pruned from the host (`acme-proxy audit cleanup`) or by
//! `audit.retention_days`; a panel session that could delete audit history
//! would make the history prove nothing, since the first thing a stolen session
//! would do is use it. That is also why neither handler here takes
//! [`AuthenticatedWrite`](crate::webadmin::session::AuthenticatedWrite) and why
//! `tests/admin_api.rs::mutating_endpoints()` has no entry for `/api/audit`.
