Module documentation for 2.0.2
Depends on 13 packages
(full list with versions ) :
base ,
base-compat ,
containers ,
deepseq ,
hashable ,
integer-logarithms ,
QuickCheck ,
semigroupoids ,
tagged ,
transformers ,
universe-base ,
universe-reverse-instances ,
unordered-containers In mathematics, a lattice is a partially ordered set in which every two
elements x
and y
have a unique supremum (also called a least upper bound, join, or x /\ y
)
and a unique infimum (also called a greatest lower bound, meet, or x \/ y
).
This package provide type-classes for different lattice types, as well
as a class for the partial order.
2.0.2 (2020-02-18)
Add Algebra.Lattice.Stacked
#99
2.0.1 (2019-07-22)
Add (PartialOrd a, PartialOrd b) => PartialOrd (Either a b)
instance
2 (2019-04-17)
Reduce to three classes (from six): Lattice
, BoundedMeetSemiLattice
,
BoundedJoinSemiLattice
.
The latter two names are kept to help migration.

instance into own module
Const
and Identity
instances
added fromBool
Add Lexicographic
, Ordered
and Op
newtypes
1.4.1 (2015-10-26)
MINIMAL
pragma in with GHC 7.8
Add DEPREACTED
pragma for meet
and join
,
use infix version \/

relaxed constraint for BoundedLattice (Levitated a)
added instances to Dropped
, Levitated
and Lifted
:
from base
NFData
Hashable
