Length directive added

We're extremely happy to announce the release of the @length directive.

You can now set both min and max values for the length of a field value or list:

type Post @model {
  title: String @length(min: 10, max: 255)
  tags: [String] @length(max: 7)
}

Now if you try to create a Post that doesn't bide by the rules you'll get an error.

mutation {
  postCreate(input: { title: "Length di" }) {
    post {
      id
      title
      tags
    }
  }
}

{
  "data": null,
  "errors": [
    {
      "message": "Invalid value for argument \"title\", length 9 is too short, must be more than 10",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ]
    }
  ]
}
