Function std.datetime.date.TimeOfDay.toString
Converts this TimeOfDay to a string.
string toString() pure nothrow @safe const;
void toString(W)
(
ref W writer
) const
if (isOutputRange!(W, char));
This function exists to make it easy to convert a TimeOfDay to a
string for code that does not care what the exact format is - just that
it presents the information in a clear manner. It also makes it easy to
simply convert a TimeOfDay to a string when using functions such
as to!string, format, or writeln which use toString to convert
user-defined types. So, it is unlikely that much code will call
toString directly.
The format of the string is purposefully unspecified, and code that
cares about the format of the string should use toISOString,
toISOExtString, or some other custom formatting function that
explicitly generates the format that the code needs. The reason is that
the code is then clear about what format it's using, making it less
error-prone to maintain the code and interact with other software that
consumes the generated strings. It's for this same reason that
TimeOfDay has no fromString function, whereas it does have
fromISOString and fromISOExtString.
The format returned by toString may or may not change in the future.
