type DataId id = (DataIdPost id, DataIdPost (NameOrRdrName id)) Source #

type DataIdPost id = (Data id, Data (PostRn id NameSet), Data (PostRn id Fixity), Data (PostRn id Bool), Data (PostRn id Name), Data (PostRn id (Located Name)), Data (PostRn id [Name]), Data (PostRn id id), Data (PostTc id Type), Data (PostTc id Coercion), Data (PostTc id id), Data (PostTc id [Type]), Data (PostTc id ConLike), Data (PostTc id [ConLike]), Data (PostTc id HsWrapper), Data (PostTc id [FieldLabel])) Source #

type family NameOrRdrName id where ... Source #

Follow the id, but never beyond Name. This is used in a HsMatchContext, for printing messages related to a Match

Equations

NameOrRdrName Id = Name 
NameOrRdrName Name = Name 
NameOrRdrName RdrName = RdrName 

type OutputableBndrId id = (OutputableBndr id, OutputableBndr (NameOrRdrName id)) Source #

Constraint type to bundle up the requirement for OutputableBndr on both the id and the NameOrRdrName type for it
