Enum member isStringSerializable

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.

Example

import std.conv;

// represented as a string when serialized
static struct S {
	int value;

	// dummy example implementations
	string toString() const { return value.to!string(); }
	static S fromString(string s) { return S(s.to!int()); }
}

static assert(isStringSerializable!S);
