1//! # ironflow-engine
2//!
3//! Workflow orchestration engine for **ironflow**.
4//!
5//! Workflows are defined as Rust-native handlers implementing
6//! [`WorkflowHandler`](handler::WorkflowHandler). Handlers receive a
7//! [`WorkflowContext`](context::WorkflowContext) and can chain step outputs,
8//! use native `if`/`else`/`match` for conditional branching, and execute
9//! steps in parallel.
10//!
11//! Handlers can be executed inline or enqueued for a background worker.
12//!
13//! ## Custom operations
14//!
15//! Implement [`Operation`](operation::Operation) to define custom step types
16//! (e.g. GitLab, Gmail, Slack) that integrate into the workflow lifecycle.
17//! Call [`WorkflowContext::operation()`](context::WorkflowContext::operation)
18//! inside a handler to execute them with full step tracking.
19//!
20//! ## Testing handlers
21//!
22//! [`TestEngine`](testing::TestEngine) runs a handler against an in-memory
23//! store with mocked shell, HTTP, agent and approval steps, so a handler's
24//! logic can be asserted without a server, a worker or a real process.
25//!
26//! # Example
27//!
28//! ```no_run
29//! use ironflow_engine::prelude::*;
30//! use std::future::Future;
31//! use std::pin::Pin;
32//!
33//! struct DeployWorkflow;
34//!
35//! impl WorkflowHandler for DeployWorkflow {
36//! fn name(&self) -> &str { "deploy" }
37//! fn execute<'a>(&'a self, ctx: &'a mut WorkflowContext) -> HandlerFuture<'a> {
38//! Box::pin(async move {
39//! let build = ctx.shell("build", ShellConfig::new("cargo build")).await?;
40//! ctx.agent("review", AgentStepConfig::new(
41//! &format!("Review: {}", build.stdout())
42//! )).await?;
43//! Ok(())
44//! })
45//! }
46//! }
47//! ```
