dietTraits

Marks a struct as a Diet traits container.

A traits struct can contain any of the following:

string translate(string) - A function that takes a string and returns the translated version of that string. This is used for translating the text of nodes marked with & at compile time. Note that the input string may contain string interpolations.
void filterX(string) - Any number of compile-time filter functions, where "X" is a placeholder for the actual filter name. The first character will be converted to lower case, so that a function filterCss will be available as :css within the Diet template.
SafeFilterCallback[string] filters - A dictionary of runtime filter functions that will be used to for filter nodes that don't have an available compile-time filter or contain string interpolations.
alias processors = AliasSeq!(...) - A list of callables taking a Document to modify its contents
HTMLOutputStyle htmlOutputStyle - An enum to configure the output style of the generated HTML, e.g. compact or pretty
