## Design goals

* Helper functionality to work with MDC.

## Usage

```clojure

(ns readme.usage

  (:require [clojure.tools.logging :as log]

            [strojure.slf4j-mdc.core :as mdc]))

(defn- update-user

  [user-id, data]

  (with-open [_ (mdc/put-closeable "user-id" (str user-id))

              _ (mdc/put-closeable "empty" nil)]

    (log/debug "Update user" data)))

(comment

  (update-user 100 {:name "Name"})

  ;; DEBUG readme.usage [ user-id=100 ]

  ;; - Update user {:name Name}

  (with-open [_ (mdc/put-closeable "request-id" "64024bf5-862a-4e9f-a827-b924fc04f6d8")]

    (update-user 100 {:name "Name"}))

  ;; DEBUG readme.usage [ request-id=64024bf5-862a-4e9f-a827-b924fc04f6d8, user-id=100 ]

  ;; - Update user {:name Name}

  )
