lib.rs

//! # solari-sdk
//!
//! Rust binding for the Solari sandbox SDK (core surface). Talks the same wire
//! protocol as the reference `@solarisdk/core` TypeScript package:
//!
//! - **REST** to the gateway for session lifecycle (create/connect/get/kill) and
//!   the one-shot `/exec` fast path.
//! - **Control WebSocket** (newline-delimited JSON-RPC) for everything a live
//!   session does: `commands`, `files`, `code.run`, and the client-side `git`
//!   namespace.
//!
//! ```no_run
//! use solari::{Client, ClientOptions, CreateOptions, RunOptions};
//!
//! # async fn ex() -> Result<(), solari::SolariError> {
//! let client = Client::new(ClientOptions::new("slr_live_…", "https://gw.example.com"))?;
//! let sbx = client.create(CreateOptions { template: Some("base".into()), ..Default::default() }).await?;
//! let out = sbx.commands().run("echo", RunOptions::new().args(["hello"])).await?;
//! println!("exit={} stdout={}", out.exit_code, out.stdout);
//! let status = sbx.git().status(Some("/repo")).await?;
//! println!("branch={} clean={}", status.branch, status.clean);
//! # Ok(()) }
