fx: Modular effectful computations with explicit environments and errors

[ effects, library, mit, resources, unclassified ] [ Propose Tags ] [ Report a vulnerability ]

A lightweight library for writing effectful computations with explicit environment dependencies and error handling. Provides value-based abstractions for effects without deep monad transformer stacks.

Key features: explicit env/err types, composable and safe resource management and concurrency, and compatibility with Ports and Adapters architecture.
