purescript-either
The Either
type provides is used to represent values that can be one of two possibilities. For example, Either Int Number
can be used in a place where either integers or floating point numbers are acceptable.
A common use for this type is error handling, where by convention the Left
constructor carries error messages and the Right
constructor carries expected values (“Right
is right”). This convention is used as the Functor
, Applicative
, Monad
, etc. instances all operate on the Right
part of the Either
.
