Examples OnceEvery

OnceEvery example

OnceEvery

This example shows once-only and periodic logging helpers.

What it demonstrates

• LogmeI_Once(...)
• LogmeI_Every(...)
• The same helpers in std::format style when available

Notes

• ..._Once prints only the first matching call.
• ..._Every limits output by time interval.
