Struct WrappedChannel

source 
pub struct WrappedChannel {
    inner: Channel,
}
Expand description

A service wrapper that hacks the gRPC request and response for observability.

  • Inject the TracingContext obtained from the current tracing span into the HTTP headers of the request. The server can then extract the TracingContext from the HTTP headers with the TracingExtract middleware. See also TracingExtract in the common_service crate.

  • Add the path of the request (indicating the gRPC call) to the response headers. The error reporting can then include the gRPC call name in the message.
