serializeToJson

Serializes the given value to JSON.

The following types of values are supported:

Json: Used as-is
null: Converted to Json.Type.null_
bool: Converted to Json.Type.bool_
float, double: Converted to Json.Type.float_
short, ushort, int, uint, long, ulong: Converted to Json.Type.int_
BigInt: Converted to Json.Type.bigInt
string: Converted to Json.Type.string
T[]: Converted to Json.Type.array
T[string]: Converted to Json.Type.object
struct: Converted to Json.Type.object
class: Converted to Json.Type.object or Json.Type.null_

All entries of an array or an associative array, as well as all R/W properties and all public fields of a struct/class are recursively serialized using the same rules.

Fields ending with an underscore will have the last underscore stripped in the serialized output. This makes it possible to use fields with D keywords as their name by simply appending an underscore.

The following methods can be used to customize the serialization of structs/classes:

Json toJson() const;
static T fromJson(Json src);

string toString() const;
static T fromString(string src);

The methods will have to be defined in pairs. The first pair that is implemented by the type will be used for serialization (i.e. toJson overrides toString).

Json serializeToJson(T value)
void serializeToJson(R destination, T value)
void

(
R
T
)
(
R destination
,
auto ref T value
)
if (
isOutputRange!(R, char) ||
isOutputRange!(R, ubyte)
)

Examples

struct Foo {
	int number;
	string str;
}

Foo f;

f.number = 12;
f.str = "hello";

string json = serializeToJsonString(f);
assert(json == `{"number":12,"str":"hello"}`);
Json jsonval = serializeToJson(f);
assert(jsonval.type == Json.Type.object);
assert(jsonval["number"] == Json(12));
assert(jsonval["str"] == Json("hello"));
