CasCap.Common.Abstractions

Core interface definitions shared across the CasCap ecosystem. This project provides the foundational contracts that other CasCap libraries and applications may depend upon.

Purpose

This library contains no concrete implementations — only interfaces and abstractions that define the contracts between components.

Target frameworks: netstandard2.0, net8.0, net9.0, net10.0

Interfaces

Interface Description
IAppConfig Marker interface implemented by all application configuration records to allow easy identification and generic constraint usage
IFeature<T> Identifies a service launched via a bitwise feature-flag enum — exposes the FeatureType property and an ExecuteAsync entry point
IEventSink<T> Generic event sink contract. Domain events are fanned out to every registered IEventSink<T> implementation in parallel
ILocalCache Abstraction for an in-process cache provider supporting Get, Set, Delete, and DeleteAll
IMyBlob Represents a blob with associated metadata (bytes, DateCreatedUtc, BlobName, SizeInBytes, HasImage)
INotifier Abstracts a notification service capable of sending and receiving messages with optional attachment support
INotificationMessage Represents an outgoing notification message (text, sender, recipients, attachments)
INotificationAttachment Metadata for an attachment received as part of a notification (Id, ContentType)
INotificationGroup Represents a named group in a notification service (Id, Name, members)
INotificationResponse Response returned after sending a notification (Timestamp)
IReceivedNotification Represents a notification received from an external messaging service (Sender, GroupId, Message, attachments)
IAzBlobStorageConfig Exposes Azure Blob Storage connection properties (endpoint/connection string, container name, health check probe type) for feature-specific configuration records
IAzTableStorageConfig Exposes Azure Table Storage connection properties (endpoint/connection string, health check probe type) for feature-specific configuration records
IFeatureConfig<T> Pairs with IFeature<T> to carry the enabled EnabledFeatures flags into the BackgroundService launcher
IKubeAppConfig Exposes Kubernetes-specific runtime properties (node name, pod name, namespace, pod IP, service account name)
IMetricsConfig Exposes OpenTelemetry metric configuration (metric name prefix, OTel service name)

Enums

Type Description
KubernetesProbeTypes [Flags] enum for Kubernetes container health probe types: None, Readiness, Liveness, Startup

IEventSink<T> Contract

Task InitializeAsync(CancellationToken cancellationToken);
Task WriteEvent(T @event, CancellationToken cancellationToken = default);
IAsyncEnumerable<T> GetEvents(string? id = null, int limit = 1000, CancellationToken cancellationToken = default);
Task HousekeepingAsync(IReadOnlyCollection<string> validIds, CancellationToken cancellationToken = default);

InitializeAsync and HousekeepingAsync have default no-op implementations so that sink authors only need to implement WriteEvent and GetEvents.

Dependencies

The only valid dependencies for this library are other Abstractions-style libraries.
