Format
An enum representing the printf-like formatting characters that must be supported by all logging backends. It is important to note that while backends must accept any of these format specifiers, they are not obliged to implement all specified formatting behavior.
The default term formatter takes care of supporting all these options when expressed in their normal '%X' form (including flags, width and precision). Custom messages parsers must convert arguments into one of these forms before passing then through to the backend.

Entries
Formats a Unicode code-point. This formatting rule can be applied to any character or integral numeric value, providing that isValidCodePoint returns true. Note that if the argument cannot be represented losslessly as an integer, it must be considered invalid.
Formats the argument using hexadecimal exponential form. This formatting option is primarily useful when debugging issues with the precise bit-wise representation of doubles because no rounding of the value takes place.
Functions
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants.
