Module grpc 

Available on crate features grpc and http only.

gRPC helpers for serving tonic services. gRPC helpers for serving tonic services from Spin components.

This module provides a thin integration layer between the Spin HTTP subsystem and tonic-generated gRPC servers. Tonic’s generated server types (e.g. GreeterServer<T>) implement tower_service::Service over HTTP requests, so they can accept Spin’s incoming Request directly.

Example

use spin_sdk::http::{IntoResponse, Request};
use spin_sdk::http_service;
#[http_service]
async fn handler(req: Request) -> impl IntoResponse {
    spin_sdk::grpc::serve(GreeterServer::new(MyGreeter), req).await
}

Functions

serve

Serve a gRPC request by forwarding it to a tower service.
