MonadError

A basic monad interface, allowing abstract manipulation of effectful values, represented using the type constructor F.

A computation yielding results of type T is represented as a value of type F[T]. Such values: * can be transformed using map * can be run in sequence using flatMap * errors can be handled using handleError * and new computations can be created using unit, eval and suspend

To use convenient .map, .flatMap syntax, make sure an implicit instance of MonadError is in scope, and import: import sttp.monad.syntax._. This adds the appropriate extension methods.
