Frameworkeither

Frameworkeither is a cross-language software framework that standardizes result and error handling using an Either-like construct. The central idea is to propagate success and failure values through a chain of computations without relying on exceptions, enabling clearer failure semantics and easier testing.

Core concepts include the Left and Right variants, a set of combinators such as map and flatMap (or then/andThen equivalents), and a fold or pattern-matching mechanism to extract values. The design emphasizes type safety, composability, and predictable control flow in both synchronous and asynchronous code paths. Language bindings typically expose a familiar API surface for teams working in JavaScript, Python, Rust, or other ecosystems.

Architecture includes a minimal core library that defines the Either type and utilities, plus adapters for embedding the construct into existing runtimes and frameworks. A bridge or interop layer aims to allow seamless use across language boundaries, supported by serialization formats and adapters for logging, validation, and retry policies.

Typical workflows involve wrapping a service call in an Either, sequencing operations with combinators, collecting multiple results, and finally handling the outcome with a single pattern: success is processed, while failure is logged or transformed into user-friendly errors.

Reception and status: frameworkeither is a niche project with several language bindings and ongoing discussions about semantics, performance, and ergonomics. It is used primarily by teams seeking explicit error semantics and testable pipelines, rather than as a universal error mechanism across all projects.
