Struct aws_lambda_runtime_proxy::LambdaRuntimeApiClient

pub struct LambdaRuntimeApiClient<ReqBody>(/* private fields */);

An http client for the Lambda Runtime API.

Implementations

impl<ReqBody: Body + Send + 'static> LambdaRuntimeApiClient<ReqBody>

pub async fn new() -> Self

where ReqBody::Data: Send, ReqBody::Error: Into<Box<dyn Error + Send + Sync>>,

Create a new client and connect to the runtime API.

impl LambdaRuntimeApiClient<Incoming>

pub async fn forward(req: Request<Incoming>) -> Result<Response<Full<Bytes>>>

Send a request to the runtime API and return the response.

Methods from Deref<Target = SendRequest<ReqBody>>

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

Polls to determine whether this sender can be used yet for a request.

If the associated connection is closed, this returns an Error.

pub async fn ready(&mut self) -> Result<(), Error>

Waits until the dispatcher is ready

If the associated connection is closed, this returns an Error.

pub fn is_ready(&self) -> bool

Checks if the connection is currently ready to send a request.

Note

This is mostly a hint. Due to inherent latency of networks, it is possible that even after checking this is ready, sending a request may still fail because the connection was closed in the meantime.

pub fn is_closed(&self) -> bool

Checks if the connection side has been closed.

pub fn send_request( &mut self, req: Request<B> ) -> impl Future<Output = Result<Response<Incoming>, Error>>

Sends a Request on the associated connection.

Returns a future that if successful, yields the Response.

Note

There are some key differences in what automatic things the Client does for you that will not be done here:

• Client requires absolute-form Uris, since the scheme and authority are needed to connect. They aren’t required here.
• Since the Client requires absolute-form Uris, it can add the Host header based on it. You must add a Host header yourself before calling this method.
• Since absolute-form Uris are not required, if received, they will be serialized as-is.
