Crate babble_bridge 

BabbleSim + Zephyr nRF RPC simulation bridge.

This crate provides three things:

• Test harness (spawn_zephyr_rpc_server_with_socat) — spawn a full BabbleSim simulation from Rust integration tests.
• xtask CLI (xtask::cli_main) — docker, zephyr-setup, and run-bsim commands that downstream crates can re-export.
• Programmatic setup API (xtask::fetch_prebuilt_binaries, xtask::zephyr_setup) — call from a downstream build.rs or any Rust code without shelling out.

Test harness usage

use std::collections::HashSet;
use std::path::Path;

let tests_dir = Path::new(concat!(env!("CARGO_MANIFEST_DIR"), "/tests/sockets"));
let (mut processes, socket_path) =
    babble_bridge::spawn_zephyr_rpc_server_with_socat(tests_dir, "my_test");

// … run test logic, write/read via a UnixStream to socket_path …

processes.search_stdout_for_strings(HashSet::from([
    "<inf> nrf_ps_server: Initializing RPC server",
]));

Modules

xtask

Xtask commands (docker, zephyr-setup, run-bsim) and programmatic API.

Structs

TestProcesses

Owns all child processes spawned for a single simulation run and accumulates their stdout output for later inspection.
