Included from CythonClients.pyx, this file defines the core adapter between the C++ async future calls and Python asyncio futures. The C++ classes defined in ClientsWrapper.h and ClientsWrapper.cpp take these callbacks and call into them from the IO thread. The callbacks examine the result, extract the exception if one occurred, and then schedule setting the result on the future to be safely executed in the asyncio loop. }} {{#program:services}} {{#service:supportedFunctions}} cdef void {{service:name}}_{{function:name}}_callback( cFollyTry[{{#function:return_type}}{{> clients/cython_return_type_cpp_type}}{{/function:return_type}}]&& result, PyObject* userdata ) noexcept: {{> clients/callback_body}} {{/service:supportedFunctions}} {{#service:interactions}} {{#service:supportedFunctions}} cdef void {{service:parent_service_name}}_{{service:name}}_{{function:name}}_callback( cFollyTry[{{#function:return_type}}{{> clients/cython_return_type_cpp_type}}{{/function:return_type}}]&& result, PyObject* userdata ) noexcept: {{> clients/callback_body}} {{/service:supportedFunctions}} {{/service:interactions}} {{/program:services}}
