Question about formatting #7

Closed jay-sridharan closed 1 year ago

I just had a small question on a design decision: why did you choose to write your own serialization rather than use an existing library like fmtlib, or simply vsnprintf? Was this to support lazy evaluation?

Thank you for all the work on the library - it looks great!

Thanks!

As you say, it is lazily evaluated, no formatting happens on the calling thread but on the background one. All the message-related information is passed on a single chunk of memory. The format string is passed as a pointer.
This a plain C logging library with C++ wrappers, that rules out fmtlib. It probably also predates fmtlib, at least fmtlib wasn't popular when this was written.
