Wasm Wasmtime

This one's for when you need to run WebAssembly outside the browser. It covers the wasmtime runtime from CLI basics through Rust embedding, which is where it gets interesting for production use. The fuel metering section is what you want if you're running untrusted code and need hard limits on CPU consumption. It also walks through the component model and WIT interfaces, which is the newer typed approach to WASM modules rather than raw exports. The WASI preview2 coverage is solid for filesystem and networking APIs. If you're building serverside WASM infrastructure or need to sandbox plugins in a Rust app, this gives you the practical commands and code patterns without the usual WebAssembly evangelism.
