Bringing WebAssembly to constrained devices with Rust: Runtimes, tooling, and real-world tradeoffs
In this talk, we will share the insights we gained while building Myrmic, our open-source Rust middleware for distributed systems, with a particular focus on our microcontroller firmware that enables running WebAssembly on resource-constrained targets such as Nordic and ESP devices. Our entire stack is Rust-based—from Embassy firmware and the embedded HAL to the Wasm toolchain and the runtimes themselves. We will outline the requirements that running Wasm in no_std environments imposes on runtim
