Tuple3IOOps<T1, T2, T3>

extension Tuple3IOOps<T1, T2, T3> on Record

Provides additional functions on a tuple of 3 IOs.

Properties

parTupled extension no setter

IO<Record> get parTupled

Creates a new IO that will return the tuple of all items if they all evaluate successfully. If any item fails or is canceled, the first instance encountered will be returned. Items are evaluated asynchronously.

Available on Record, provided by the Tuple3IOOps<T1, T2, T3> extension

Implementation

IO<(T1, T2, T3)> get parTupled => IO.both(init.parTupled, last).map((t) => t.$1.appended(t.$2));

tupled extension no setter

IO<Record> get tupled

Creates a new IO that will return the tuple of all items if they all evaluate successfully. If any item fails or is canceled, the first instance encountered will be returned. Each item is evaluated synchronously.

Available on Record, provided by the Tuple3IOOps<T1, T2, T3> extension

Implementation

IO<(T1, T2, T3)> get tupled => init.tupled.flatMap((x) => last.map(x.appended));

Methods

flatMapN() extension

IO<T4> flatMapN<T4>(IO<T4> Function(T1, T2, T3) fn)

Creates a new IO that applies fn to the values of each respective tuple member if all IOs succeed. If any item fails or is canceled, the first instance encountered will be returned. Each item is evaluated synchronously.

Available on Record, provided by the Tuple3IOOps<T1, T2, T3> extension

Implementation

IO<T4> flatMapN<T4>(Function3<T1, T2, T3, IO<T4>> fn) => tupled.flatMap(fn.tupled);

mapN() extension

IO<T4> mapN<T4>(T4 Function(T1, T2, T3) fn)

Creates a new IO that applies fn to the values of each respective tuple member if all IOs succeed. If any item fails or is canceled, the first instance encountered will be returned. Each item is evaluated synchronously.

Available on Record, provided by the Tuple3IOOps<T1, T2, T3> extension

Implementation

IO<T4> mapN<T4>(Function3<T1, T2, T3, T4> fn) => tupled.map(fn.tupled);

parMapN() extension

IO<T4> parMapN<T4>(T4 Function(T1, T2, T3) fn)

Creates a new IO that applies fn to the values of each respective tuple member if all IOs succeed. If any item fails or is canceled, the first instance encountered will be returned. Each item is evaluated synchronously.

Available on Record, provided by the Tuple3IOOps<T1, T2, T3> extension

Implementation

IO<T4> parMapN<T4>(Function3<T1, T2, T3, T4> fn) => parTupled.map(fn.tupled);
