durable_lambda_builder/lib.rs
1//! Builder-pattern API approach for durable Lambda handlers.
2//!
3//! This crate provides a builder-pattern API for writing durable Lambda functions
4//! with step-by-step configuration. Use [`handler`] to create a
5//! [`DurableHandlerBuilder`], then call [`.run()`](DurableHandlerBuilder::run)
6//! to start the Lambda runtime.
7//!
8//! # Quick Start
9//!
10//! ```no_run
11//! use durable_lambda_builder::prelude::*;
12//!
13//! #[tokio::main]
14//! async fn main() -> Result<(), lambda_runtime::Error> {
15//! durable_lambda_builder::handler(|event: serde_json::Value, mut ctx: BuilderContext| async move {
16//! let order = ctx.step("validate_order", || async {
17//! Ok::<_, String>(serde_json::json!({"id": 123, "valid": true}))
18//! }).await?;
19//! Ok(serde_json::json!({"order": order}))
20//! })
21//! .run()
22//! .await
23//! }
24//! ```
