Main data types
Unique identifier.
The type of unique identifiers that are used in many places in GHC
for fast ordering and equality tests. You should generate these with
the functions from the UniqSupply module
These are sometimes also referred to as "keys" in comments in GHC.
class Uniquable a where Source #
Class of things that we can obtain a Unique from

uNIQUE_BITS :: Int Source #
Constructors, destructors and operations on Uniques
pprUniqueAlways :: Unique -> SDoc Source #
mkUniqueGrimily :: Int -> Unique Source #
isValidKnownKeyUnique :: Unique -> Bool Source #
The interface file symbol-table encoding assumes that known-key uniques fit in 30-bits; verify this.
See Note [Symbol table representation of names] in BinIface for details.
