Description

This is where we define a mapping from Uniques to their associated known-key Names for things associated with tuples and sums. We use this mapping while deserializing known-key Names in interface file symbol tables, which are encoded as their Unique. See Note [Symbol table representation of names] for details.

# Looking up known-key names

knownUniqueName :: Unique -> Maybe Name #

Get the `Name` associated with a known-key `Unique`.

# Getting the `Unique`s of `Name`s

## Anonymous sums

mkSumTyConUnique :: Arity -> Unique #

mkSumDataConUnique :: ConTagZ -> Arity -> Unique #

isSumTyConUnique :: Unique -> Maybe Arity #

## Tuples

### Vanilla

mkTupleTyConUnique :: Boxity -> Arity -> Unique #

mkTupleDataConUnique :: Boxity -> Arity -> Unique #

isTupleTyConUnique :: Unique -> Maybe (Boxity, Arity) #

This function is an inverse of `mkTupleTyConUnique`

isTupleDataConLikeUnique :: Unique -> Maybe (Boxity, Arity) #

This function is an inverse of `mkTupleTyDataUnique` that also matches the worker and promoted tycon.
