static BinaryFormatter.formatToDeclare(value, f, pos, output)¶

Convert a format string to a titus.pfaast.BinaryFormatter.Declare object.

Parameters:	value (titus.pfaast.TaskResult) – task result, usually Python code in a string, passed to the format declarer f (string) – format string pos (string or None) – source file location from the locator mark for error messages output (bool) – True for pack, False for unpack
Return type:	titus.pfaast.BinaryFormatter.Declare subclass
Returns:	format declarer
