ZSTM

Submerges the error case of an Either into the STM. The inverse operation of STM.either.

Accesses the environment of the transaction.

Accesses the environment of the transaction to perform a transaction.

Atomically performs a batch of operations in a single transaction.

Checks the condition, and if it's true, returns unit, otherwise, retries.

Evaluate each effect in the structure from left to right, collecting the the successful values and discarding the empty cases.

Collects all the transactional effects in a collection, returning a single transactional effect that produces a collection of values.

Collects all the transactional effects in a set, returning a single transactional effect that produces a set of values.

Collects all the transactional effects, returning a single transactional effect that produces Unit.

Equivalent to collectAll(i).unit, but without the cost of building the list of results.

Collects the first element of the Iterable[A] for which the effectual function f returns Some.

Similar to Either.cond, evaluate the predicate, return the given A as success if predicate returns true, and the given E as error otherwise

Kills the fiber running the effect.

Kills the fiber running the effect with a RuntimeException that contains the specified message.

Returns a value modelled on provided exit status.

Retrieves the environment inside an stm.

Determines whether any element of the Iterable[A] satisfies the effectual predicate f.

Returns a value that models failure in the transaction.

Filters the collection using the specified effectual predicate.

Filters the set using the specified effectual predicate.

Filters the collection using the specified effectual predicate, removing all elements that satisfy the predicate.

Filters the set using the specified effectual predicate, removing all elements that satisfy the predicate.

Returns an effectful function that extracts out the first element of a tuple.

Returns an effect that first executes the outer effect, and then executes the inner effect, returning the value from the inner effect, and effectively flattening a nested effect.

Folds an Iterable[A] using an effectual function f, working sequentially from left to right.

Folds an Iterable[A] using an effectual function f, working sequentially from right to left.

Determines whether all elements of the Iterable[A] satisfy the effectual predicate f.

Applies the function f to each element of the Collection[A] and returns a transactional effect that produces a new Collection[B].

Applies the function f to each element of the Set[A] and returns a transactional effect that produces a new Set[B].

Applies the function f to each element of the Iterable[A] and returns a transactional effect that produces Unit.

Equivalent to foreach(as)(f).unit, but without the cost of building the list of results.

Lifts an Either into a STM.

Lifts a function R => A into a URSTM[R, A].

Lifts an effectful function whose effect requires no environment into an effect that requires the input to the function.

Lifts an Option into a STM.

Lifts a Try into a STM.

Returns the identity effectful function, which performs no effects

Runs onTrue if the result of b is true and onFalse otherwise.

Iterates with the specified transactional function. The moral equivalent of:

var s = initial

while (cont(s)) {
 s = body(s)
}

s

Returns an effect with the value on the left part.

Loops with the specified transactional function, collecting the results into a list. The moral equivalent of:

var s  = initial
var as = List.empty[A]

while (cont(s)) {
 as = body(s) :: as
 s  = inc(s)
}

as.reverse

Loops with the specified transactional function purely for its transactional effects. The moral equivalent of:

var s = initial

while (cont(s)) {
 body(s)
 s = inc(s)
}

Sequentially zips the specified effects using the specified combiner function.

Merges an Iterable[ZSTM] to a single ZSTM, working sequentially.

Creates an STM value from a partial (but pure) function.

Feeds elements of type A to a function f that returns an effect. Collects all successes and failures in a tupled fashion.

Reduces an Iterable[ZSTM] to a single ZSTM, working sequentially.

Replicates the given effect n times. If 0 or negative numbers are given, an empty Iterable will return.

Performs this transaction the specified number of times and collects the results.

Performs this transaction the specified number of times, discarding the results.

Requires that the given ZSTM[R, E, Option[A]] contain a value. If there is no value, then the specified error will be raised.

Returns an effect with the value on the right part.

Returns an effectful function that extracts out the second element of a tuple.

Accesses the specified service in the environment of the effect.

Effectfully accesses the specified service in the environment of the effect.

Accesses the specified services in the environment of the effect.

Returns an effect with the optional value.

Returns an STM effect that succeeds with the specified value.

Suspends creation of the specified transaction lazily.

Returns an effectful function that merely swaps the elements in a Tuple2.

The moral equivalent of if (!p) exp

The moral equivalent of if (!p) exp when p has side-effects

Feeds elements of type A to f and accumulates all errors in error channel or successes in success channel.

This combinator is lossy meaning that if there are errors all successes will be lost. To retain all information please use partition.

Feeds elements of type A to f and accumulates all errors in error channel or successes in success channel.

This combinator is lossy meaning that if there are errors all successes will be lost. To retain all information please use partition.

Feeds elements of type A to f until it succeeds. Returns first success or the accumulation of all errors.

The moral equivalent of if (p) exp

Runs an effect when the supplied PartialFunction matches for the given value, otherwise does nothing.

Runs an effect when the supplied PartialFunction matches for the given effectful value, otherwise does nothing.

The moral equivalent of if (p) exp when p has side-effects
