(entity env)
(entity {:keys [parser] :as env} attributes)

Fetch the entity according to the ::entity-key. If the entity is an IAtom, it will be derefed.

If a second argument is sent, calls the parser against current element to guarantee that some fields are loaded. This is useful when you need to ensure some values are loaded in order to fetch some more complex data. NOTE: When using this call with an explicit vector of attributes the parser will not be invoked for attributes that already exist in the current value of the current entity.

Like map-reader, but it has extra options (read from the environment): map-key-transform: (fn [key]) will transform the key on the AST before trying to match with entity key map-value-transform: (fn [key value]) will transform the output value after reading from the entity.

The reason to have a separated reader is so the plain version (map-reader) can be faster by avoiding checking the presence of transform functions.
