ErrInvalidKey indicates a key is invalid for some reason.

ErrMissingRequiredField is returned when calling 'Finish' on a NodeAssembler for a Struct that has not has all required fields set.

ErrNoSuchField may be returned from lookup functions on the Node interface when a field is requested which doesn't exist, or from assigning data into on a MapAssembler for a struct when the key doesn't match a field name in the structure (or, when assigning data into a ListAssembler and the list size has reached out of bounds, in case of a struct with list-like representations!).

ErrNotUnionStructure means data was fed into a union assembler that can't match the union.

ErrUnmatchable is the error raised when processing data with IPLD Schemas and finding data which cannot be matched into the schema.

ImplicitValue is an sum type holding values that are implicits.

typesystem.Type is an union interface; each of the `Type*` concrete types in this package are one of its members.

schema.TypedLinkNode is a superset of the schema.TypedNode interface, and has one additional behavior.

schema.TypedNode is a superset of the datamodel.Node interface, and has additional behaviors.

TypedPrototype is a superset of the datamodel.Nodeprototype interface, and has additional behaviors, much like TypedNode for datamodel.Node.

TypeKind is an enum of kind in the IPLD Schema system.
