LanguageExt.Rx

LanguageExt.Rx are the 'Reactive Extensions' extensions for the language-ext functional programming framework.

The framework uses and abuses the features of C# to provide a pure functional-programming 'Base Class Library' that, if you squint, can look like extensions to the language itself. The desire here is to make programming in C# much more robust by helping the engineer's inertia flow in the direction of declarative and pure functional code rather than imperative.

Using these techniques for large code-bases can bring tangible benefits to long-term maintenance by removing hidden complexity and by easing the engineer's cognitive load.

Traits

The traits are major feature of v5+ language-ext that makes generic programming with higher-kinds a reality. Check out Paul's series on Higher Kinds to get a deeper insight.

Value traits

These work a little like NewType but they impart semantic meaning and some common operators for the underlying value.

Location Feature Description
Core DomainType<SELF, REPR> Provides a mapping from SELF to an underlying representation: REPR
Core Identifier <SELF> Identifiers (like IDs in databases: PersonId for example), they are equivalent to DomaintType with equality.
Core VectorSpace<SELF, SCALAR> Scalable values; can add and subtract self, but can only multiply and divide by a scalar. Can also negate.
Core Amount <SELF, SCALAR> Quantities, such as the amount of money in USD on a bank account or a file size in bytes. Derives VectorSpace, IdentifierLike, DomainType, and is orderable (comparable).
Core LocusLike <SELF, SCALAR, DISTANCE> Works with space-like structures. Spaces have absolute and relative distances. Has an origin/zero point and derives DomainType, IdentifierLike, AmountLike and VectorSpace. DISTANCE must also be an AmountLike<SELF, REPR, SCALAR>.
