Struct GrpcOtelInterceptor 

pub struct GrpcOtelInterceptor;

Available on crate feature grpc only.

A gRPC interceptor that injects the current tracing context into the request metadata.

Use this interceptor to make sure that DataDog traces are connected between the services when calling the gRPC service on another server.

Example

use tonic::transport::{Endpoint, Channel};

use prima_bridge::{GrpcOtelInterceptor, GrpcOtelInterceptedService};

async fn make_grpc_service() -> Result<QuotePreviewServiceClient<GrpcOtelInterceptedService<Channel>>, Box<dyn std::error::Error>> {
    let url = "http://...";
    let channel = Endpoint::new(url)?.connect().await?;
    // QuotePreviewServiceClient is a tonic-generated gRPC client from [https://github.com/primait/es-engine-schema]
    Ok(QuotePreviewServiceClient::with_interceptor(channel, GrpcOtelInterceptor))
}
