Features

• RPC Frameworks - Provides a high-performance framework for executing type-safe remote procedures across network nodes using shared schemas.
• Resource Lifecycle Managers - Provides a system for predictable allocation and automated cleanup of distributed resources to prevent memory leaks.
• Bidirectional Multiplexing - Routes asynchronous data streams and procedure calls between distinct execution contexts using a shared message bus.
• Flow Control - Employs backpressure and flow-control mechanisms to manage bidirectional data streaming and prevent memory overflow.
• Remote Stub Disposal - Manages the lifecycle of remote stubs to trigger server-side resource reclamation once all references are released.
• Cap'n Proto RPC Implementations - Provides a communication system for type-safe remote procedure calls and distributed object interaction based on Cap'n Proto.
• Stream Multiplexing - Implements techniques for running multiple independent data streams over a single physical network connection.
• Schema-Based Server Generation - Automatically generates client and server stubs from shared service schemas to enforce strict type contracts.
• Value Serialization - Implements mechanisms for marshalling primitives and plain objects into binary buffers for network transfer.
• Capability-Based Access Controls - Governs access to remote resources using unforgeable tokens and object-capability-based authorization.
• Object Capability Models - Implements a security model where every object reference carries a capability defining the allowed operations.
• Shared Object Abstractions - Implements shared object abstractions that allow developers to interact with distributed data structures as if they were local.
• Reference Counting Mechanisms - Uses reference counting to track remote object ownership and automate memory reclamation when references are released.
• Remote Object Stubs - Provides remote stubs that allow class instances to be shared and invoked across the network without serializing the entire object.
• RPC Over WebSocket - Enables bidirectional, asynchronous remote procedure calls over persistent WebSocket connections.
• High-Performance Networking - Reduces network latency and overhead by multiplexing data streams and batching requests over persistent connections.
• Promise-Based Batching - Groups dependent remote procedure calls into a single network request to reduce round-trip latency.
• RPC Call Batching - Groups multiple remote procedure calls into a single network request to reduce latency and improve efficiency.
• Promise Pipelining - Reduces network round trips by chaining dependent remote procedure calls together via promise pipelining.
• Remote Value Transformations - Allows executing server-side callbacks to modify values before transmission, minimizing the amount of data transferred over the network.
• Bidirectional Streams - Supports full-duplex message exchange with flow control and backpressure for high-volume data streaming.
