ion2json not working

[WebFreak001]

I'm trying to get a JSON representation of IonDescribedValue like so:

IonException deserializeFromIon(scope const char[][] symbolTable, IonDescribedValue v)
{
    import mir.ion.value;
    import mir.ion.conv;

    rawJson = ion2json(inputValue.data);
    return null;
}

however this ends in this exception:

assert(deserializeJson!JsonToken(serializeJson(JsonToken("1"))).rawJson == "1");

[WebFreak001]

similarly trying to call serializeJson on the IonDescribedValue gives this compilation error:

IonDescribedValue isn's supposed to be serializable directly. But you can do serialize it with symbol table:

            static if (__traits(hasMember, serializer, "putKeyId"))
            {
                alias unwrappedSerializer = serializer;
            }
            else
            {
                import mir.ser.unwrap_ids;
                auto unwrappedSerializer = unwrapSymbolIds(serializer,  symbolTable);
            }
            unwrappedSerializer.serilalizeValue(value);

[9il]

BTW, it feels you are doing something wrong.

Could you use JsonAlgebraic instead of JsonToken?

For example, deserializeJson!JsonAlgebraic or deserializeText!JsonAlgebraic (for better JSON error messages).

[WebFreak001]

ah JsonAlgebraic might be a better option. Can I then later convert the JsonAlgebraic to custom types through mir-ion somehow?

My idea with JsonToken was that it would optimally just be a slice of the source input for minimal overhead, but that didn't really seem possible with how deserialization works.

You would need to write your own recursive constructor in the custom type.

My idea with JsonToken was that it would optimally just be a slice of the source input for minimal overhead, but that didn't really seem possible with how deserialization works.

Yes, it isn't possible. Json is converted to ion and then deserialized. The ion data is located on the stack or allocated using C library functions and scoped buffers.

If you need to read JSON from a file you can use deserializeJsonFile.

In the same time, unlikely you may need to care about performance. It would be very fast anyway.

The fastest way is deserialization of a custom D types directly form json.

For example:

struct S
{
    double[] array;
    string name;
}
auto s = `{"array":[1.0,4.8],"name":"example"}`.deserializeJson!S;

[WebFreak001]

I'm trying to use mir-ion with JSON-RPC where I basically have a wrapper JSON that contains additional information like method name and request id and then has the params, which are later passed to the proper handler through a custom type.

I feel like wrappers like this should be common enough that it should be somehow possible to have some kind of any type that can be later converted to the actual resolved type. With painlessjson before I simply stored a JSONValue object everywhere where I either didn't want to implement any (de)serialization but still wanted to give the user access to custom fields or to delay (de)serialization for later/earlier.

struct Request
{
    SumType!(string, int) id;
    string method;
    JSONValue params;
}

[9il]

Mir doesn't support JSONValue and SumType, you can use Mir's JsonAlgebraic and Variant instead.

struct Request
{
    import mir.algebraic: Variant;
    import mir.algebraic_alias: JsonAlgebraic; // it is a recursive Variant.
    Variant!(string, int) id;
    string method;
    import mir.serde;
    @serdeOptional @serdeIgnoreDefault
    JsonAlgebraic params;
}

[9il]

Ah, for deserialization please use deserializeDynamicJson - it can handle internal JsonAlgebraic data.

[WebFreak001]

I've got most things I needed rewritten now, but JsonAlgebraic doesn't seem to work with all strings.

I tried this code:

import std.stdio;

import mir.serde;
import mir.algebraic_alias.json : JsonAlgebraic;
import mir.deser.json : deserializeDynamicJson;

void main()
{
    auto v = deserializeDynamicJson!JsonAlgebraic(`{"a":[1,"world",false,null]}`);
    writeln(v);
}

which crashes at runtime with
