Function lambda_runtime::run

pub async fn run<A, F, R, B, S, D, E>(handler: F) -> Result<(), Error>
where
    F: Service<LambdaEvent<A>>,
    F::Future: Future<Output = Result<R, F::Error>>,
    F::Error: Debug + Display,
    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.

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)
}
