Decodable

public protocol Decodable

Decodable protocol is used to specify how a FaunaDB value returned by the server is converted to other Swift data structures.

For example:

struct Point { let x, y: Int }

extension Point: Decodable {
    init?(value: Value) throws {
        try self.init(
            x: value.get("data", "position", "x") ?? 0
            y: value.get("data", "position", "y") ?? 0
    }
}

//...

let point: Point? = databaseValue.get()

Documentation describing data conversion can be found in the FaunaDB.Field struct.
