Re: How do I use spec and deftype together?
Just in case someone stumbles over this post, I found a simple solution which works for me: (do (require '[clojure.spec.alpha :as s]) (import '(clojure.lang ISeq)) (defprotocol Foo (foo [this])) (defrecord Bar [bar] Foo (foo [this] (.bar this))) (deftype Baz [bar] Foo (foo [this] (.bar this)) ISeq (seq [this] `(~(.bar this (s/def ::bar number?) [(s/valid? (s/keys :req-un [::bar]) (->Bar 0)) (s/valid? (s/cat :bar ::bar) (->Baz 0))]) ;[true true] -- You received this message because you are subscribed to the Google Groups "Clojure" group.

RE: How do I use spec and deftype together?
So is it best practice to implement map in the deftype to make it spec-able? Are there examples somewhere that show how to do this in a canonical way? If you want a `deftype` that is spec-able as a map, why not just use `defrecord`? Manually implementing the various map-related interfaces is a fair bit of boilerplate/work.

Spec doesn't check object fields. The defrecord case works because defrecord implements map.
