[
{
"field1": "Donald Duck",
"field2": "sample text",
"field3": 0.5675269775390624,
"h": 490,
"attrfield": [
{
"attr1": "first attribute",
"attr2": "secod attribute"
},
{
"attr1": "first attribute",
"attr2": "secod attribute"
}
]
},
{
"field1": "Mickey Mouse",
"field2": "sample text",
"field3": 0.9995269775390625,
"h": 300,
"attrfield": [
{
"attr1": "first attribute",
"attr2": "secod attribute"
},
{
"attr1": "first attribute",
"attr2": "secod attribute"
}
]
}
]

when i try to map it into a struct I reach allways the following error:
terminate called after throwing an instance of 'struct_mapping::StructMappingException'
what(): parser: unexpected character '[' at line 1

Unfortunately, the object is expected first. Arrays as the first elements are not yet supported (there is not enough time to expand the library). You can wrap your array in a structure, then everything will work.

{
  "arr": [
    {
      "field1": "Donald Duck",
      "field2": "sample text",
      "field3": 0.5675269775390624,
      "h": 490,
      "attrfield": [
        {
          "attr1": "first attribute",
          "attr2": "secod attribute"
        },
        {
          "attr1": "first attribute",
          "attr2": "secod attribute"
        }
      ]
    },
    {
      "field1": "Mickey Mouse",
      "field2": "sample text",
      "field3": 0.9995269775390625,
      "h": 300,
      "attrfield": [
        {
          "attr1": "first attribute",
          "attr2": "secod attribute"
        },
        {
          "attr1": "first attribute",
          "attr2": "secod attribute"
        }
      ]
    }
  ]
}
