Rel8.Internal.Type.Semigroup

Synopsis

class DBType a => DBSemigroup a where
- (<>.) :: Expr a -> Expr a -> Expr a

Documentation

class DBType a => DBSemigroup a where Source #

The class of DBTypes that form a semigroup. This class is purely a Rel8 concept, and exists to mirror the Semigroup class.

Methods

(<>.) :: Expr a -> Expr a -> Expr a infixr 6 Source #

An associative operation.
