explanation
Explanation
Ensures laziness of Logger calls.
You will want to wrap expensive logger calls into a zero argument
function (fn -> "string that gets logged" end).
Example:
# preferred
Logger.debug fn ->
"This happened: #{expensive_calculation(arg1, arg2)}"
end
# NOT preferred
# the interpolation is executed whether or not the info is logged
Logger.debug "This happened: #{expensive_calculation(arg1, arg2)}"
