Crate durable_lambda_builder 

Builder-pattern API approach for durable Lambda handlers.

This crate provides a builder-pattern API for writing durable Lambda functions with step-by-step configuration. Use [handler] to create a DurableHandlerBuilder, then call .run() to start the Lambda runtime.

Quick Start

use durable_lambda_builder::prelude::*;

#[tokio::main]
async fn main() -> Result<(), lambda_runtime::Error> {
    durable_lambda_builder::handler(|event: serde_json::Value, mut ctx: BuilderContext| async move {
        let order = ctx.step("validate_order", || async {
            Ok::<_, String>(serde_json::json!({"id": 123, "valid": true}))
        }).await?;
        Ok(serde_json::json!({"order": order}))
    })
    .run()
    .await
}
