sealed abstract class ZServiceBuilder[-RIn, +E, +ROut] extends AnyRef

A ZServiceBuilder[E, A, B] describes how to build one or more services in your application. Services can be injected into effects via ZIO#inject. Effects can require services via ZIO.service."

ServiceBuilder can be thought of as recipes for producing bundles of services, given their dependencies (other services).

Construction of services can be effectful and utilize resources that must be acquired and safely released when the services are done being utilized.

By default service builders are shared, meaning that if the same servicebuilder is used twice the service builder will only be allocated a single time.

Because of their excellent composition properties, service builders are the idiomatic way in ZIO to create services that depend on other services.
