hive-fressian

Generic Fressian envelope codec with an OCP handler-domain registry, packaged as a library-kind hive-addon (IAddon 0.2.0).

What it does

• hive-fressian.registry — register a domain (a named bundle of write/read handlers for one type family) once; every codec call sees the merged handlers. New type family = one register!, codec untouched.
• hive-fressian.codec — durable envelope files: header map + item stream. write-envelope! / read-envelope.
• hive-fressian.addon — IAddon record advertising the :serialization/fressian capability (no tools; consumers call the namespaces directly).

Usage

(require '[hive-fressian.registry :as registry]
         '[hive-fressian.codec :as codec])

(registry/register! :my/domain
  {:write-handlers {MyType {"my.Type" (reify WriteHandler ...)}}
   :read-handlers  {"my.Type" (reify ReadHandler ...)}})

(codec/write-envelope! "out.fressian" {:kind :my-snapshot} items)
(codec/read-envelope "out.fressian")
;; => {:header {..} :items [..]}
