bool8

Alternative Bool type stored as byte.

The standard Bool type has a Storable instance that requires the size of HTYPE_INT, i.e. usually four bytes or even more. This package provides Bool8, a boolean type with an 8 bit representation in memory. It is not a drop-in replacement for Bool though. You have to convert from or to Bool occasionally.

Starting with GHC-8.2/base-4.10 you also have Foreign.C.Types.CBool.
