Public Methods

• ::at<T as shape()>(darray $shape, arraykey $index)
  Returns the value of the field $index of $shape, throws if the field is missing
• ::idx<T as shape()>(darray $shape, arraykey $index, mixed $default = NULL): mixed
  Shapes::idx is a helper function for accessing shape field value, or getting a default if it's not set - similar to idx(), but for shapes
• ::keyExists<T as shape()>(darray $shape, arraykey $index): bool
  Check if a field in shape exists
• ::removeKey<T as shape()>(inout darray $shape, arraykey $index): void
  Removes the $index field from the $shape (passed in as an inout argument)
• ::toArray<T as shape()>(darray $shape): darray<arraykey, mixed>
• ::toDict<T as shape()>(darray $shape): dict<arraykey, mixed>
