//! - Structured JSON output
//!
//! ## Usage
//!
//! ```ignore
//! use iam_audit::{AuditLogger, AuditEvent, AuditEventKind, FileSink};
//!
//! let sink = FileSink::new("/var/log/iam-audit.jsonl").await?;
//! let logger = AuditLogger::new(sink);
//!
//! logger.log(AuditEvent::authn_success("alice", "jwt")).await?;
//! ```
