ZStream

An Emit[R, E, A, B] represents an asynchronous callback that can be called multiple times. The callback can be called with a value of type ZIO[R, Option[E], Chunk[A]], where succeeding with a Chunk[A] indicates to emit those elements, failing with Some[E] indicates to terminate with that error, and failing with None indicates to terminate with an end of stream signal.

Representation of a grouped stream. This allows to filter which groups will be processed. Once this is applied all groups will be processed in parallel and the results will be merged in arbitrary order.

Provides extension methods for streams that are sorted by distinct keys.

Submerges the error case of an Either into the ZStream.

Accesses the environment of the stream.

Accesses the environment of the stream in the context of an effect.

Creates a new ZStream from a managed effect that yields chunks. The effect will be evaluated repeatedly until it fails with a None (to signify stream end) or a Some(E) (to signify stream failure).

The stream evaluation guarantees proper acquisition and release of the ZManaged.

Creates a pure stream from a variable list of values

Creates a stream from a single value that will get cleaned up after the stream is consumed

Creates a stream from a single value that will get cleaned up after the stream is consumed

Concatenates all of the streams in the chunk to one stream.

Composes the specified streams to create a cartesian product of elements with a specified function. Subsequent streams would be run multiple times, for every combination of elements in the prior streams.

See also ZStream#zipN for the more common point-wise variant.

Creates a single-valued stream from a managed resource

Merges a variable list of streams in a non-deterministic fashion. Up to n streams may be consumed in parallel and up to outputBuffer chunks may be buffered by this operator.

Like mergeAll, but runs all streams concurrently.

Like unfoldM, but allows the emission of values to end one step further than the unfolding of the state. This is useful for embedding paginated APIs, hence the name.

Like unfoldChunk, but allows the emission of values to end one step further than the unfolding of the state. This is useful for embedding paginated APIs, hence the name.
