episode 24: WebAssembly and Rust in Practice, A Conversation with Alex Crichton.
In this episode we sit down with Alex Crichton to talk about WebAssembly and Rust in practice. We discuss how Wasm grew beyond the browser into a serious runtime for servers and plugins, and why Rust fits so well in this space.
We also explore WASI, the component model, and lessons from building Wasmtime, covering performance, security, and what it takes to run Wasm in production.
