I am using the spdlog library in a C++20 project using modules.

Using SpdLog With Modules/C++20 Gives Internal Compiler Error (MSVC 2022)

I’m using spdlog library in my high-load service. Also my service is getting requests from another service by gRPC.

For Spdlog in C++, the typical example is to declare your log inside a function, but what if you want a single log used globally?
This may be a stupid, obvious typing question that I'm just overlooking a simple explanation for, so apologies. While using spdlog, the examples are ALL declared in functions, in my case like this:
void daily_example()
{ auto daily_logger =…
