EitherSyntax

class EitherSyntax[V](either: Either[String, V])

Syntax for treating scalaz.\/ as signifiers of success or failure in a computation.

Syntax for treating scalaz.\/ as signifiers of success or failure in a computation.

The simplest usage is something like: myEither ~>? "Do I have the right?". The 'value' and log tree of the returned treelog.LogTreeSyntax.DescribedComputation will indicate success or failure depending on the value of myEither.

def ~>?(description: String): DescribedComputation[V]

Use the same description regardless of whether either is a \/- or a -\/. Equivalent to: ~>?((error: String) => s"$description - $error", description)
