JSON formatting

In general, Cuprate's JSON formatting is very similar to monerod, but there are some differences.

This is a list of those differences.

Pretty vs compact

TODO: decide when handlers are created if we should allow custom formatting.

Cuprate's RPC (really, serde_json) can be configured to use either:

• Pretty formatting
• Compact formatting

monerod uses something similar to pretty formatting.

As an example, pretty formatting:

{
  "number": 1,
  "array": [
    0,
    1
  ],
  "string": "",
  "array_of_objects": [
    {
      "x": 1.0,
      "y": -1.0
    },
    {
      "x": 2.0,
      "y": -2.0
    }
  ]
}

compact formatting:

{"number":1,"array":[0,1],"string":"","array_of_objects":[{"x":1.0,"y":-1.0},{"x":2.0,"y":-2.0}]}

Array of objects

monerod will format an array of objects like such:

{
  "array_of_objects": [{
    "x": 0.0,
    "y": 0.0,
  },{
    "x": 0.0,
    "y": 0.0,
  },{
    "x": 0.0,
    "y": 0.0
  }]
}

Cuprate will format the above like such:

{
  "array_of_objects": [
    {
      "x": 0.0,
      "y": 0.0,
    },
    {
      "x": 0.0,
      "y": 0.0,
    },
    {
      "x": 0.0,
      "y": 0.0
    }
  ]
}

Array of maps containing named objects

An method that contains outputs like this is the peers field in the sync_info method:

curl \
    http://127.0.0.1:18081/json_rpc \
    -d '{"jsonrpc":"2.0","id":"0","method":"sync_info"}' \
    -H 'Content-Type: application/json'

monerod will format an array of maps that contains named objects like such:

{
  "array": [{
    "named_object": {
      "field": ""
    }
  },{
    "named_object": {
      "field": ""
    }
  }]
}

Cuprate will format the above like such:

{
  "array": [
    {
      "named_object": {
        "field": ""
      }
    },
    {
      "named_object": {
        "field": ""
      }
    }
  ]
}
