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 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);
