Iterate over JSON Array containing JSON Objects

See more JSON Examples

Demonstrates how to load a JSON array and iterate over the JSON objects. Rust

// Loads the following JSON array and iterates over the objects:
// 
// [
// {"tagId":95,"tagDescription":"hola 1","isPublic":true},
// {"tagId":98,"tagDescription":"hola 1","isPublic":true},
// {"tagId":101,"tagDescription":"hola 1","isPublic":true},
// {"tagId":104,"tagDescription":"hola 1","isPublic":true},
// {"tagId":107,"tagDescription":"hola 1","isPublic":true},
// {"tagId":110,"tagDescription":"hola 1","isPublic":true},
// {"tagId":113,"tagDescription":"hola 1","isPublic":true},
// {"tagId":114,"tagDescription":"hola 2","isPublic":true},
// {"tagId":111,"tagDescription":"hola 2","isPublic":true},
// {"tagId":108,"tagDescription":"hola 2","isPublic":true},
// {"tagId":105,"tagDescription":"hola 2","isPublic":true},
// {"tagId":102,"tagDescription":"hola 2","isPublic":true},
// {"tagId":99,"tagDescription":"hola 2","isPublic":true},
// {"tagId":96,"tagDescription":"hola 2","isPublic":true},
// {"tagId":97,"tagDescription":"hola 3","isPublic":true},
// {"tagId":100,"tagDescription":"hola 3","isPublic":true},
// {"tagId":103,"tagDescription":"hola 3","isPublic":true},
// {"tagId":106,"tagDescription":"hola 3","isPublic":true},
// {"tagId":109,"tagDescription":"hola 3","isPublic":true},
// {"tagId":112,"tagDescription":"hola 3","isPublic":true},
// {"tagId":115,"tagDescription":"hola 3","isPublic":true},
// {"tagId":93,"tagDescription":"new tag","isPublic":true},
// {"tagId":94,"tagDescription":"new tag","isPublic":true},
// {"tagId":89,"tagDescription":"tag 1","isPublic":true},
// {"tagId":90,"tagDescription":"tag 2","isPublic":true},
// {"tagId":91,"tagDescription":"tag private 1","isPublic":false},
// {"tagId":92,"tagDescription":"tag private 2","isPublic":false}
// ]
