Source

Since v2.0.0

foldUntilEffect

Like Sink.foldWeightedEffect but with a constant cost function of 1.

Signature

declare const foldUntilEffect: <S, In, E, R>(
  s: S,
  max: number,
  f: (s: S, input: In) => Effect.Effect<S, E, R>

Source

Since v2.0.0

foldWeighted

Creates a sink that folds elements of type In into a structure of type S, until max worth of elements (determined by the costFn) have been folded.

Note

Elements that have an individual cost larger than max will force the sink to cross the max cost. See Sink.foldWeightedDecompose for a variant that can handle these cases.

Signature

declare const foldWeighted: <S, In>(options: {
  readonly initial: S
  readonly maxCost: number
  readonly cost: (s: S, input: In) => number
  readonly body: (s: S, input: In) => S
}) => Sink<S, In, In>

Source

Since v2.0.0

foldWeightedDecompose

Creates a sink that folds elements of type In into a structure of type S, until max worth of elements (determined by the costFn) have been folded.

The decompose function will be used for decomposing elements that cause an S aggregate to cross max into smaller elements. For example:

pipe(
  Stream.make(1, 5, 1),
  Stream.transduce(
    Sink.foldWeightedDecompose(
      Chunk.empty<number>(),
      4,
      (n: number) => n,
      (n: number) => Chunk.make(n - 1, 1),
      (acc, el) => pipe(acc, Chunk.append(el))
    )
  ),
  Stream.runCollect
)

The stream would emit the elements Chunk(1), Chunk(4), Chunk(1, 1).

Be vigilant with this function, it has to generate “simpler” values or the fold may never end. A value is considered indivisible if decompose yields the empty chunk or a single-valued chunk. In these cases, there is no other choice than to yield a value that will cross the threshold.

Sink.foldWeightedDecomposeEffect allows the decompose function to return an effect value, and consequently it allows the sink to fail.

Signature

declare const foldWeightedDecompose: <S, In>(options: {
  readonly initial: S
  readonly maxCost: number
  readonly cost: (s: S, input: In) => number
  readonly decompose: (input: In) => Chunk.Chunk<In>
  readonly body: (s: S, input: In) => S
}) => Sink<S, In, In>

models

Sink (interface)

A Sink<A, In, L, E, R> is used to consume elements produced by a Stream. You can think of a sink as a function that will consume a variable amount of In elements (could be 0, 1, or many), might fail with an error of type E, and will eventually yield a value of type A together with a remainder of type L (i.e. any leftovers).

Signature

export interface Sink<out A, in In = unknown, out L = never, out E = never, out R = never>
  extends Sink.Variance<A, In, L, E, R>,
