ρ: A DSL for building HTTP services with http4s

What distinguishes ρ from the http4s-core dsl?

• The http4s-core dsl defines routes in terms of partial functions using pattern matching extractors while ρ uses a set of 'rules' to match and extract information from the request.
• ρ maintains meta data such as the names of extracted parameters and their types which can be reused for tasks such as generation of Swagger documentation.
• ρ routing is implemented as an efficient tree structure as opposed to a linear search.

How does ρ compare other Scala http frameworks?

• ρ is similar in intention to the red-eyes project: maintaining metadata.
• ρ route definition feels similar to Finch and Scalatra.
