//! Comprehensive OpenRPC Example for Hero Supervisor
|
||
//!
|
||
//! This example demonstrates the complete OpenRPC workflow:
|
||
//! 1. Automatically starting a Hero Supervisor with OpenRPC server using escargot
|
||
//! 2. Building and using a mock runner binary
|
||
//! 3. Connecting with the OpenRPC client
|
||
//! 4. Managing runners (add, start, stop, remove)
|
||
//! 5. Creating and queuing jobs
|
||
//! 6. Monitoring job execution and verifying results
|
||
//! 7. Bulk operations and status monitoring
|
||
//! 8. Gracefully shutting down the supervisor
|
||
//!
|
||
//! To run this example:
|
||
//! `cargo run --example basic_openrpc_client`
|
||
//!
|
||
//! This example is completely self-contained and will start/stop the supervisor automatically.
