    Reference: FaunaDB Values

    Overview

    Value is an algebraic data type that represents the value of possible FaunaDB query responses. While it is possible to extract data out of a Value object using pattern matching, the faunadb.values.Field lets you create more complex and reusable data extractors.

    // Simple, adhoc extraction:
    value("data", "name").to[String].get
    
    // Using a reusable Field:
    val NameField = Field("data", "name").to[String]
    value(NameField).get

    Extraction can be composed:

    val refAndNameAndAge = for {
      ref <- value("ref").to[RefV]
      name <- value("data", "name").to[String]
      age <- value("data", "age").to[Int]
    } yield (ref, name, age)
    
    refAndNameAndAge.get
    
    // or
    
    val RefAndNameAndAgeField = Field.zip(
      Field("ref").to[RefV],
      Field("data", "name").to[String],
      Field("data", "age").to[Int])
    
    value(RefAndNameAndAgeField).get

    If a value may be an array, or may contain an array, the array's elements may be cast using collect:

    value("data", "tags").collect(Field.to[String]).get
    
    // or
    
    val TagsField = Field("data", "tags").collect(Field.to[String])
    value(TagsField).get
