Struct HttpClientBackend 

pub(crate) struct HttpClientBackend {
    inner: HttpTransport,
    task_group: Arc<TaskGroup>,
}

HTTP client backend for JSON-RPC.

Fields

inner: HttpTransport

task_group: Arc<TaskGroup>

Shared with the Client so driver tasks (h1 per-request, h3 connection) get cancelled when the Client stops.

Implementations

impl HttpClientBackend

pub(crate) fn new( endpoint: &Endpoint, task_group: Arc<TaskGroup>, ) -> Result<Self>

Create an HTTP/1.1 + HTTP/2 client.

pub(crate) async fn new_h3( endpoint: &Endpoint, quic_config: &ClientQuicConfig, task_group: Arc<TaskGroup>, ) -> Result<Self>

Create an HTTP/3 client (QUIC). The driver task is spawned via task_group so it gets cancelled when the Client stops.

pub(crate) async fn send_request(&self, msg: Value) -> Result<Response>

Send a JSON-RPC request and return the response.

pub(crate) async fn subscribe_h3( &self, msg: Value, ) -> Result<(Response, RequestStream<RecvStream, Bytes>)>

Subscribe over HTTP/3. Returns the initial response + recv stream.
