Source Generation

FxKit ships with a few (optional) source generators, each enabled by their respective attribute:

• [EnumMatch]: generates a Match extension method for the enum type. Useful to guarantee exhaustive matching. Each enum member will be represented as a function parameter to Match.
• [Lambda]: when used at the type level, generates a λ as a Func, allowing you to pass a type's constructor as a function. When used on a method, generates a Func for that method suffixed with λ in the name.
• [Union]: turns the record into a union type. Each member gets a λ and Of methods for constructing the member. The return type of these is the base type which makes it useful for mapping.
• [GenerateTransformer]: when used on extension methods that operate on functor types.

To use, install the FxKit.CompilerServices and FxKit.CompilerServices.Annotations packages.
