Functions

open suspend fun <B> Either<R, B>.bind(): B

Folds Either into EagerEffect, by returning B or a shift with R.

open suspend fun <B> Validated<R, B>.bind(): B

Folds Validated into EagerEffect, by returning B or a shift with R.

open suspend fun <B> EagerEffect<R, B>.bind(): B

Runs the EagerEffect to finish, returning B or shift in case of R.

open suspend fun <B> <ERROR CLASS><B>.bind(transform: (Throwable) -> R): B

suspend fun <R, B : Any> EagerEffectScope<R>.ensureNotNull(value: B?, shift: () -> R): B
