Macro Definition Documentation

◆ Must

#define Must (   condition)    Must3((condition), #condition, Here())

Like Assure() but only logs the exception if level-3 debugging is enabled and runs even when NDEBUG macro is defined. Deprecated: Use Assure() for code logic checks and throw explicitly when input validation fails.

Definition at line 75 of file TextException.h.

◆ Must3

#define Must3 (   condition,
)     Assure_(3, (condition), ("check failed: " description), (location))

Like Must() but supports custom exception message and location.

descriptionstring literal describing the condition; what MUST happen Deprecated: Use Assure2() for code logic checks and throw explicitly when input validation fails.
