Overview (reactor-core 3.7.0)

Packages
Package	Description
reactor.adapter	Adapt `Publisher` to Java 9+ `Flow.Publisher`.
reactor.core	Core components of the framework supporting extensions to the Reactive Stream programming model.
reactor.core.observability
reactor.core.publisher	Provide main Reactive APIs in `Flux` and `Mono`, as well as various helper classes, interfaces used in the composition API, variants of Flux and operator-building utilities.
reactor.core.scheduler	`Scheduler` contract and static registry and factory methods in `Schedulers`.
reactor.util	Miscellaneous utility classes, such as loggers, tuples or queue suppliers and implementations.
reactor.util.annotation
reactor.util.concurrent	Queue `suppliers and utilities` Used for operational serialization (serializing threads) or buffering (asynchronous boundary).
reactor.util.context	Miscellaneous utility classes, such as loggers, tuples or queue suppliers and implementations.
reactor.util.function	`Tuples` provide a type-safe way to specify multiple parameters.
reactor.util.retry

This document is the API specification for the Reactor Core library. Routine use of Reactor will involve the composable Reactive Streams Flux and Mono located under reactor.core.publisher.

Reactor Core is a succinct and powerful foundational library for building reactive and efficient applications on the JVM. More detailed documentation is available on the reference guide.
