Herald.Sinks.InMemory

Retains Herald log events in-memory so tests can assert against what the pipeline produced. Not intended for production — a long-running app using this sink will grow the event list unboundedly unless a capacity is set.

Part of Herald — high-performance structured logging for .NET 8, 9, and 10.

Install

dotnet add package Herald.Sinks.InMemory

The sink auto-registers into LogSinkProviderRegistry.Default via a [ModuleInitializer] on assembly load. No manual RegisterAll(...) or With*SinkProviders() call is required — dotnet add package is the whole workflow.

Sink kind: in_memory (the identifier the Dashboard form and JSON config use to reference this sink).

Capabilities

  • Snapshot read via Events (safe to iterate while logging continues)
  • Clear() for per-test isolation
  • Optional FIFO cap via Capacity constructor argument
  • Thread-safe via internal lock

Limitations

  • Unbounded by default — do not use in production without a cap
  • Snapshot allocates an array on every Events read (test-scale N is fine)
  • No persistence — events disappear when the process exits

Tier & runtime

  • Edition: Community — works on the free Apache 2.0 Herald.Core. No license key required.
  • AOT-compatible: yes
  • Targets: .NET 8 / 9 / 10
  • Thread safety: Thread-safe via per-sink lock on Log / Events / Clear.

Vendor

Configuration

Per-sink config form lives in configuration*.mmpform at the package root and inside the assembly as an embedded resource. The Herald Dashboard renders it at runtime; JSON config follows the same shape. See CAPABILITY.yaml shipped at the package root for the full manifest (schema reference: CAPABILITY-SCHEMA.md).
