Sinks in Effect

Overview

A Sink is a consumer of stream elements that produces a result:

Sink<A, In, L, E, R>;
// A  - Result type (what sink produces)
// In - Input element type (what sink consumes)
// L  - Leftover type (unconsumed elements)
// E  - Error type
// R  - Required environment

Sinks are the counterpart to Streams - while Streams produce data, Sinks consume it.
