Scalars

Scalar types are not divisible, they have no fields of their own. The scalar types automatically available to you in a Sudograph schema are:

• Boolean
• Date
• Float
• ID
• Int
• String

Boolean

A Boolean value maps to a Rust bool.

type User {
    id: ID!
    verified: Boolean!
}

Date

A Date value maps to a Rust String for storage and a chrono::DateTime for filtering.

type User {
    id: ID!
    dateOfBirth: Date!
}

Float

A Float value maps to a Rust f32.

type User {
    id: ID!
    height: Float!
}

ID

An ID value maps to a Rust String. All Sudograph object types must have a field called id of type ID.

type User {
    id: ID!
}

Int

An Int value maps to a Rust i32.

type User {
    id: ID!
    age: Int!
}

String

A String value maps to a Rust String.

type User {
    id: ID!
    username: String!
}
