Networking Example — Rust

Source: apps/rust/example_net/src/lib.rs | WASM Demo{:target="_blank"}

Exercises the full networking stack with a pass/fail test framework: netif configuration, DNS resolution, TCP/UDP sockets, HTTP client (GET/POST/PUT), SNTP time sync, MQTT pub/sub, and embedded HTTP server.

Language-specific patterns

This example uses the ove Rust crate with no_std support. Error handling uses Result<(), ove::Error>. Shared state uses atomics where possible. The ove::shared! macro provides safe static initialization.

See the overview for architecture details and the full API list.
