Function lambda_runtime::run

pub async fn run<A, F, R, B, S, D, E>(handler: F) -> Result<(), Error>
where
    F: Service<LambdaEvent<A>, Response = R>,
    F::Future: Future<Output = Result<R, F::Error>>,
    F::Error: for<'a> Into<Diagnostic<'a>> + Debug,
    A: for<'de> Deserialize<'de>,
    R: IntoFunctionResponse<B, S>,
    B: Serialize,
    S: Stream<Item = Result<D, E>> + Unpin + Send + 'static,
    D: Into<Bytes> + Send,
    E: Into<Error> + Send + Debug,

Starts the Lambda Rust runtime and begins polling for events on the Lambda Runtime APIs.

If you need more control over the runtime and add custom middleware, use the Runtime type directly.

Example

use lambda_runtime::{Error, service_fn, LambdaEvent};
use serde_json::Value;

#[tokio::main]
async fn main() -> Result<(), Error> {
    let func = service_fn(func);
    lambda_runtime::run(func).await?;
    Ok(())
}

async fn func(event: LambdaEvent<Value>) -> Result<Value, Error> {
    Ok(event.payload)
}
