Coost
Coost is a concurrent network framework and coroutine scheduler designed for building high-performance TCP, HTTP, and RPC services. It provides a set of tools for handling non-blocking IPv4 and IPv6 communication, integrating SSL encryption and a lightweight execution engine that manages concurrent tasks using shared stacks.
The project features a specialized JSON RPC implementation for exchanging structured data over encrypted connections and a high-performance logging system. This logging infrastructure supports topic-based routing, frequency filtering, and automated stack trace capture for system observability.
The framework covers a broad range of system capabilities, including asynchronous HTTP client and server hosting, slab-based memory allocation to reduce resident footprints, and a command line tooling suite for argument parsing and configuration file generation. It also includes utilities for cryptographic hashing, unit test execution, and performance benchmarking.
