Enum member isFormMap
Tests if a given type is suitable for storing a web form.
enum isFormMap(T)
= isStringMap!T || isJsonLike!T;
Types that define iteration support with the key typed as string
and
the value either also typed as string
, or as a Json
like value. The latter case specifically requires a
property that
is tested for equality with T
, as well as a
method.
