Enum member isStringSerializable
Checks if a given type has a string serialization representation.
A class or struct type is string serializable if it defines a pair of
toString
/
fromString
methods. Any class or struct type that
has this trait will be serialized by using the return value of it's
toString
method instead of the original value.
Declaration
enum isStringSerializable(T) = is(typeof(T .init .toString()) == string) && is(typeof(T .fromString("")) == T);
Example
import std .conv;
// represented as the boxed value when serialized
static struct Box(T) {
T value;
}
template BoxPol(S)
{
auto toRepresentation(S s) {
return s .value;
}
S fromRepresentation(typeof(S .init .value) v) {
return S(v);
}
}
static assert(isPolicySerializable!(BoxPol, Box!int));
