## Description

The Cloudflare Workers Rust SDK is a toolchain and framework for building high-performance serverless functions using Rust. It compiles code into WebAssembly modules that execute within a sandboxed host environment at the edge.

The project provides a typed remote procedure call system for invoking functions across different worker instances and utilizes procedural macros for mapping these distributed interfaces. It uses trait-based bindings and standardized wrappers to provide type-safe access to platform services and web-standard request and response objects.

The SDK covers a broad range of edge capabilities, including HTTP middleware for request routing and WebSocket management, as well as asynchronous background processing via message queues. It integrates various storage primitives such as distributed key-value stores, R2 object storage, and D1 SQLite databases, alongside stateful coordination through durable objects. Additionally, it includes primitives for calling artificial intelligence models for text generation and data analysis.
