logger library

Classes

ConsoleOutput: Pretty-prints log records to stdout with optional ANSI colors.
LogConfig: Snapshot of controller configuration (for remote control / diagnostics).
LogController: Central log dispatcher.
LogEnricher: Enricher adds fields to every log record passing through the pipeline.
LogEvent: A point-in-time log event.
LogFilter: Filter criteria for log subscriptions and queries.
LogOutput: Interface for log output backends.
LogRecord: Base type for all log records flowing through the pipeline.
LogRedactor: Redacts sensitive fields from log record data.
LogScope: Lightweight logging handle bound to a scope name and controller.
LogSpan: A completed operation span with duration.
LogSpanHandle: Handle to an active (in-progress) span.
LogSpanStart: Marks the beginning of a span.
RingBufferOutput: In-memory circular buffer that keeps the last N log records.
RpcLogOutput: Log output that sends records to a remote peer via RPC.
RpcLogResponder: Accepts log records from a remote peer and feeds them into a local LogController.
RpcLogServiceCaller: Client-side API for connecting to a remote log service.
RpcLogServiceResponder: Exposes local logs to remote peers for diagnostics and remote control.
SamplingConfig: Per-level sampling configuration.
SamplingState: Runtime sampling state that tracks record counts per level within the current interval.

RpcLogConnectionCheck = bool Function(): Callback type for checking if the RPC connection is active.
RpcLogSendCallback = Future<void> Function(Map<String, dynamic> json): Callback type for sending a log record over RPC. The implementation should serialize and send the record to the remote peer. Returns a future that completes when the send is done (or fails).
RpcLogStreamCall = Stream<Map<String, dynamic>> Function(String method, Map<String, dynamic> request): Callback type for streaming RPC calls to the remote log service.
RpcLogUnaryCall = Future<Map<String, dynamic>> Function(String method, Map<String, dynamic> request): Callback types for RPC calls to the remote log service.
RpcLogVoidCall = Future<void> Function(String method, Map<String, dynamic> request): Callback type for fire-and-forget RPC calls to the remote log service.
SpanCompleteCallback = void Function(LogSpan span): Callback for when a span ends and should be emitted.
SpanEventCallback = void Function(LogEvent event): Callback for emitting live events from within a span.
SpanStartCallback = void Function(LogSpanStart start): Callback for emitting span start.
