Crate durable_lambda_closure 

Closure-native API approach for durable Lambda handlers.

This crate provides a closure-based API for writing durable Lambda functions with minimal boilerplate. Use run as the single entry point — it handles all lambda_runtime and DurableContext wiring internally.

Quick Start

use durable_lambda_closure::prelude::*;

async fn handler(
    event: serde_json::Value,
    mut ctx: ClosureContext,
) -> Result<serde_json::Value, DurableError> {
    let order = ctx.step("validate_order", || async {
        Ok::<_, String>(serde_json::json!({"id": 123, "valid": true}))
    }).await?;
    Ok(serde_json::json!({"order": order}))
}

#[tokio::main]
async fn main() -> Result<(), lambda_runtime::Error> {
    durable_lambda_closure::run(handler).await
}
