Crate muse_codes 

muse-codes

Typed Rust SDK for Meta’s Muse Code terminal coding agent. Models the machine-readable JSONL event stream of headless runs (muse exec --json): an event-sourced journal of envelope records (MuseRecord) whose payloads cover command intake, run lifecycle, task lifecycle, and streamed output.

Types are derived from captured real CLI output (committed under test_cases/), captured via the credential-free --provider echo mode. Payload types not yet observed deserialize as MusePayload::Unknown rather than failing, and the envelope keeps the raw payload so round-trips are byte-faithful.

Features

• types — serde models only; wasm32-unknown-unknown compatible.
• async-client (default) — Tokio client spawning muse exec --json.

Quick start

use muse_codes::{ExecRun, MuseExecBuilder, MusePayload, Provider};

let run = ExecRun::spawn(
    &MuseExecBuilder::new("summarize this repo").provider(Provider::Meta),
).await?;

let terminal = run.wait_terminal(|record| {
    if let Ok(MusePayload::RunOutputDelta(d)) = record.typed_payload() {
        print!("{}", d.text);
    }
}).await?;
println!("\nterminal: {}", terminal.terminal);
