[kespinola]

Goal

Add a catch all parser which mimics the response of getTransaction with jsonParsed.

Strategy

The parser should trigger for all programs. It should return all the same info user expected from jsonParsed. Since vixen provides instruction callbacks the acount info should be imbedded with the instruction.

    vixen::Runtime::builder()
        .instruction(Pipeline::new(SolanaRPCParser, [Handler]))
        .build(config)
        .run();

[kespinola]

As of now parser program ID is used to form the dragon's mouth subscription. For this parser the programs the user wants to subscribe to aren't known until build or runtime.

Consider expanding config or adding a pre-register phase to allow user to add additional filters to the dragons mouth subscription.
