Module wasm_builder 

WebAssembly component builder with multi-language support

This module provides functionality to build WebAssembly components from various source languages, with support for both WASI Preview 1 and Preview 2 (component model) targets.

Supported Languages

• Rust: cargo build --target wasm32-wasip1 or cargo component build
• Go: TinyGo compiler with WASI target
• Python: componentize-py for component model
• TypeScript/JavaScript: jco/componentize-js
• AssemblyScript: asc compiler
• C: Clang with WASI SDK
• Zig: Native WASI support

Usage

use std::path::Path;
use zlayer_builder::wasm_builder::{build_wasm, WasmBuildConfig, WasiTarget};

let config = WasmBuildConfig {
    language: None,  // Auto-detect
    target: WasiTarget::Preview2,
    optimize: true,
    ..Default::default()
};

let result = build_wasm(Path::new("./my-plugin"), config).await?;
println!("Built {} WASM at {}", result.language, result.wasm_path.display());
