Struct lambda_web_adapter::Adapter

impl Adapter

pub fn new(options: &AdapterOptions) -> Adapter

Create a new Adapter instance. This function initializes a new HTTP client to talk with the web server.

pub fn with_client(self, client: Client) -> Self

Switch the default HTTP client with a different one.

pub fn register_default_extension(&self)

Register a Lambda Extension to ensure that the adapter is loaded before any Lambda function associated with it.

pub async fn check_init_health(&mut self)

Check if the web server has been initialized. If Adapter.async_init is true, cancel this check before Lambda’s init 10s timeout, and let the server boot in the background.

pub async fn run(self) -> Result<(), Error>

Run the adapter to take events from Lambda.

Trait Implementations§
