pub struct LambdaHandler<R>
where
    R: Debug + Serialize + 'static,
{ /* private fields */ }

Routes incoming AWS events to their corresponding handlers based on their types and names.

Implementations

impl<R: Debug + Serialize> LambdaHandler<R>

pub fn new() -> Self

Creates a new LambdaHandler.

Returns

A new LambdaHandler instance.

pub fn route<E, F, Fut>(self, event_name: &str, handler: F) -> Self

where E: AwsEvent + 'static, F: Fn(LambdaEvent<E>) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<R, LambdaError>> + Send + 'static,

Adds a route to the router.

Arguments

• event_name - The name of the AWS event to route.
• handler - The function to handle the routed event.

Returns

fn poll_ready(&mut self, _: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Checks if the service is ready to process a request.

fn call(&mut self, req: LambdaEvent<Value>) -> Self::Future
