Crate rusty_junctions_library_generation_proc_macro

Crate providing the essential functionality for the compile time generation of the rusty_junctions crate to an arbitrary pattern arity.

The intention of this crate is to be called from within the root of the rusty_junctions crate library in order to generate all of the essential components:

• The PartialPattern and TerminalPartialPattern patterns that leverage the compiler to provide the type safety guarantees provided to the clients at compile time, preventing a number of difficult to debug runtime issues.

• When applying the then_do method to a PartialPattern or a TerminalPartialPattern we are required to pass in a closure. The function_transform are used to transform the types of the closure to accept Message as the arguments.

• The type of the transformed closures also depend on the arity of the associated pattern, so we are required to generate this programmatically. This is done internally using the function_types Macro.

• Finally the JoinPattern derive macro which is used to derive the implementation of the JoinPattern trait from the PartialPattern or TerminalPartialPattern.

See the function level documentation for further details.
