continuum_store_memory 3.0.0

In-memory EventStore implementation for the continuum event sourcing library.

example/main.dart

/// In-Memory Event Store - Quick Start Example
///
/// This example shows the minimal setup for using InMemoryEventStore.
/// The in-memory store is perfect for:
///   - Unit and integration tests (fast, isolated, no cleanup needed)
///   - Rapid prototyping during development
///   - Scenarios where events don't need to survive app restarts
///
/// For comprehensive examples of event sourcing patterns (sessions, concurrency,
/// atomic operations, etc.), see the continuum package examples.
///
/// To run:
///   cd example
///   dart pub get
///   dart run build_runner build
///   dart run main.dart
