Package: effect
Module: Effect
Dynamically provides an implementation for a service using an effect.
Details
This function allows you to provide an implementation for a service dynamically by using another effect. The provided effect is executed to produce the service implementation, which is then made available to the consuming effect. This is particularly useful when the service implementation itself requires asynchronous or resource-intensive initialization.
For example, you can use this function to lazily initialize a database connection or fetch configuration values from an external source before making the service available to your effect.
Signature
declare const provideServiceEffect: { <I, S, E1, R1>(tag: Context.Tag<I, S>, effect: Effect<NoInfer<S>, E1, R1>): <A, E, R>(self: Effect<A, E, R>) => Effect<A, E | E1, R1 | Exclude<R, I>>; <A, E, R, I, S, E1, R1>(self: Effect<A, E, R>, tag: Context.Tag<I, S>, effect: Effect<NoInfer<S>, E1, R1>): Effect<A, E | E1, R1 | Exclude<R, I>>; }
