• Type-Safe Remote Calls - Enforces type safety across distributed calls by defining RPC types via shared protobuf schemas.
• Async-Await Flow Control - Implements a non-blocking asynchronous execution model to handle concurrent RPC calls efficiently.
• gRPC and HTTP TLS Securings - Encrypts communication between clients and servers using TLS with configurable certificates and mutual authentication.
• SSL/TLS Connection Security - Secures network traffic using transport layer security to ensure data privacy and peer authenticity.
• TLS Traffic Encryption - Secures communication channels between clients and backend services using SSL/TLS encryption.
• Transport Layer Security - Provides transport-level encryption and authentication for secure network communication channels.
• Protocol Buffer Implementations - Includes a full protocol buffers implementation for encoding and decoding messages from service definitions.
• RPC - Allows attaching and extracting detailed error metadata to programmatically communicate specific failure reasons.
• API Error Handling - Implements a detailed error model to convey complex failure states beyond simple numeric status codes.
• RPC Infrastructure Toolkits - Provides distributed systems capabilities such as service reflection, standardized health monitoring, and client-side load balancing.
• Connection Lifecycle Managers - Manages the connection lifecycle, including keep-alive settings, timeouts, and lazy connection establishment.
