ugrpc::client::MiddlewareCallContext Class Reference

#include <userver/ugrpc/client/middlewares/base.hpp>

Detailed Description

Context for middleware-specific data during gRPC call.

It is created for each gRPC Call and it stores aux. data used by middlewares. Each registered middleware is called by Middleware::Handle with the context passed as an argument. A middleware may access Call and initial request (if any) using the context.

Examples

samples/grpc_middleware_service/src/middlewares/client/middleware.cpp, and samples/grpc_middleware_service/src/middlewares/client/middleware.hpp.
