rustwasm/wasm-bindgen
Wasm Bindgen
wasm-bindgen 是一个绑定生成器和互操作层，旨在映射 WebAssembly 和 JavaScript 边界之间的数据类型和函数。它充当外部函数接口，合成必要的样板代码以实现 Rust 和浏览器运行时之间的双向通信。
该项目生成胶水代码和包装器，自动化复杂类型的转换，允许将 Rust 函数导出为 JavaScript 模块，并将浏览器 API 导入到 Rust 中。它使用过程宏来定义这些接口，并根据 Rust 类型定义合成绑定。
该系统通过线性内存指针传递来管理内存，并使用 JavaScript 管理的内存句柄处理资源交换。它依赖于与 C ABI 兼容的调用约定，在模块和宿主之间传递原始整数和浮点数。
Features
- WebAssembly Glue Code Generators - Generates the necessary JavaScript and Rust glue code to automate complex type conversion between the two environments.
- FFI Export Macros - Uses procedural macros to annotate Rust functions and types for export to the JavaScript environment.
- Rust Language Binding Generators - Generates the necessary boilerplate and language bindings to call Rust functions from JavaScript and vice versa.
- JavaScript Function Invocations - Provides the ability to invoke specific JavaScript functions and browser APIs from within Rust code.
- WebAssembly-JavaScript Interoperability - Manages the exchange of complex data types, functions, and memory between WebAssembly and JavaScript.
- Foreign Function Interfaces - Implements a foreign function interface for mapping complex types across the WebAssembly and host boundary.
- WebAssembly Bridges - Creates high-level communication bindings to export compiled WebAssembly functions to JavaScript environments.
- Function Exports - Exposes Rust functions and types as modules that can be called by the JavaScript runtime.
- Rust WebAssembly Integrations - Provides the core machinery for calling Rust from JavaScript and utilizing browser APIs within Rust.
- Interop Layers - Acts as a compatibility layer translating memory and type representations between Rust and the browser runtime.
- Rust-to-JS Type Synthesis - Analyzes Rust type definitions to automatically synthesize memory layouts and conversion logic for JavaScript.
- C ABI Compatibility - Implements a low-level calling convention compatible with the C ABI for passing primitives between Wasm and the host.
- Linear Memory Sharing - Passes memory addresses and lengths to share large data structures between Rust and JavaScript without copying buffers.
- Wasm Memory Handles - Wraps Wasm memory pointers in JavaScript objects to track and manage allocated Rust resources.
- Rust Frontend Frameworks - Facilitates building web-based user interfaces and application logic using Rust.
- High-Performance UI Logic - Enables moving compute-intensive tasks from JavaScript to Rust for higher performance in web applications.
- Language Implementations - Library for Rust and JavaScript interoperability.
- WebAssembly Interoperability - High-level interface for Rust and JavaScript module interaction.
