Rebuilding Prime Video UI with Rust and WebAssembly

Alexandru Ene features details of a new UI SDK in Rust for Prime Video that targets living room devices.

I'll talk about challenges in this space, because living room devices are things like set top boxes, gaming consoles, streaming sticks, TVs. It has a couple of virtual machines, some rendering backend, which mainly connects the higher-level stuff we download to things like OpenGL and other graphics APIs, networking. As you can see, things are over icons and under, it's just a prototype, but it felt so much nicer and responsive compared to what you could get on a device that it just convinced people instantly that it's worth the risk of building a UI in Rust and WebAssembly.
