When attached to a function this attribute will configure the start section of the Wasm executable to be emitted, executing the tagged function as soon as the Wasm module is instantiated. The #[wasmedge_bindgen] macro is needed for the compiler tools to auto-generate the correct code to pass call parameters from Go to WebAssembly. First and foremost, wasm-bindgen is designed to be lightweight and a "pay only for what you use" mentality. This book is about wasm-bindgen, a Rust library and CLI tool that facilitate high-level interactions between Wasm modules and JavaScript. Note: Unfortunately, the maintainers behind wit-bindgen didn’t want to add support for Wasmer upstream, so we had to do a hard-fork in order to make things work with Wasmer. 49 then rerun wasm build. exe) on the rustwasm downloads page.
