Method layer

lambda-runtime/src/runtime.rs:150–161

Add a new layer to this runtime. For an incoming request, this layer will be executed before any layer that has been added prior. # Example ```no_run use lambda_runtime::{layers, Error, LambdaEvent, Runtime}; use serde_json::Value; use tower::service_fn; #[tokio::main] async fn main() -> Result<(), Error> { let runtime = Runtime::new(service_fn(echo)).layer( layers::TracingLayer::new() ); runtim

(self, layer: L)

    /// }
    /// ```
    pub fn layer<L>(self, layer: L) -> Runtime<L::Service>
    where
        L: Layer<S>,
        L::Service: Service<LambdaInvocation, Response = (), Error = BoxError>,
    {
        Runtime {
            client: self.client,
            config: self.config,
            service: layer.layer(self.service),
            concurrency_limit: self.concurrency_limit,
        }
    }
}
