CSharpFunctionalExtensions
CSharpFunctionalExtensions is a functional programming library for C# that provides a framework of monadic containers, pipeline orchestration tools, and immutable domain object patterns. It implements the result pattern to handle operation success and failure as values, reducing the reliance on exceptions for control flow.
The library enables railway-oriented programming by chaining multiple operations into sequences that execute only upon the success of previous steps. It provides specialized wrappers for optional and result types to minimize null checks and nested conditional logic, alongside a base implementation for creating immutable value objects defined by their properties.
The project covers a broad range of functional capabilities, including the aggregation of multiple independent operation outcomes, collection filtering for optional types, and the mapping of functional states to standard HTTP responses for web interfaces. It also includes mechanisms for wrapping functional chains within atomic transactions.
Features
- Functional Programming Libraries - Implements functional programming patterns like Result and Option as a library for the C# language.
- Railway Oriented Programming - Implements the railway-oriented programming pattern to chain operations into success and failure tracks.
- Result Patterns - A framework for handling operation success and failure as values instead of using exceptions for control flow.
- Optional Containers - Uses optional containers to handle missing values without relying on null checks.
- Extension Methods - Implements functional operators as C# extension methods to enable declarative operation chaining.
- Functional Programming Patterns - Applies functional programming patterns to C# to make logic more predictable and reduce side effects.
- Functional Pipeline Composition - Enables the composition of execution pipelines where subsequent steps depend on the success of previous ones.
- Error Handling Patterns - Treats errors as explicit return values to avoid exception-based control flow.
- Monadic Error Handling - Uses monadic container types to manage operation failures as values instead of throwing exceptions.
- Monadic Containers - Provides monadic containers like Option and Result to wrap values and manage computational effects.
- Sequence Pipelines - Implements a railway-oriented pipeline that chains operations and executes only upon the success of previous steps.
- Value Objects - Implements immutable value objects defined by their properties to ensure domain state consistency.
- Optional Value Types - Implements data structures that represent values that may be absent to prevent null-pointer errors.
- Result-Type Integration - Integrates result types into the type system to explicitly signify success or failure.
- Result Aggregators - Combines multiple independent outcome containers into a single aggregated result based on collective success.
- Monadic Query Syntax - Allows chaining multiple operations using query syntax to reduce nested conditionals for result types.
- Domain-Driven Designs - Provides patterns for aligning software architecture with complex business domains through immutable value objects.
- Task Result Aggregation - Aggregates multiple operation outcomes into a single unified result structure.
- Functional Programming - Core functional programming extensions for C#.
