eff

apply a function to an Eff value using the applicative instance

use the internal effect as one of the stack effects

peel-off the only present effect

peel-off the only present effect, using an Applicative instance where possible

An Eff[R, A] value can be transformed into an Eff[U, A] value provided that all the effects in R are also in U

use the applicative instance of Eff to traverse a list of values, then flatten it

create a impure value from an union of effects and a continuation

create a pure value

base runner for an Eff value having no effects at all

This runner can only return the value in Pure because it doesn't known how to interpret the effects in Impure

get the pure value if there is no effect

create an Eff[R, A] value from an effectful value of type T[V] provided that T is one of the effects of R

use the applicative instance of Eff to sequence a list of values

use the applicative instance of Eff to traverse a list of values

create an Eff value for ()
