Struct data type

A STRUCT is a composite data type that allows you to group multiple fields of different types into a single unit. Each field in a struct has a name and can hold a value of any supported data type, including other structs.

Type Constraints

• Field names must be strings
• Field values can be of any valid Flavius data type
• Structs can be nested to create complex data structures
• Field names must be unique within the same struct

Create struct

Structs are defined using curly braces {} with field-value pairs separated by commas. Field names are followed by a colon and their corresponding values:

{field1: value1, field2: value2, ...}

Struct literals

-- Basic struct
RETURN {name: "John", age: 30, active: true} AS person
 
-- Nested struct
RETURN {
  user: {name: "John", age: 30},
  address: {city: "San Francisco", country: "USA"}
} AS userProfile

Accessing Fields

You can access struct fields using dot notation:

WITH {name: "John", age: 30} AS person
RETURN person.name, person.age
