toucan2.jdbc.result-set
Implementation of a custom next.jdbc result set builder function, builder-fn, and the default
implementation; [[reduce-result-set]] which is used to reduce results from JDBC databases.

builder-fnclj
(builder-fn conn₁ model₂ rset opts)Return the next.jdbc builder function to use to create the results when querying a model. By default, this
uses instance-builder-fn, and returns Toucan 2 instances; but if you want to use plain maps you can use one of the
other builder functions that ships with next.jdbc, or write your own custom builder function.
builder-fn is defined in toucan2.jdbc.result-set (toucan2/jdbc/result_set.clj:25).
It caches methods using a methodical.impl.cache.watching.WatchingCache.
It uses the method combination methodical.impl.combo.threaded.ThreadingMethodCombination
with the threading strategy :thread-last.
It uses the dispatcher methodical.impl.dispatcher.multi_default.MultiDefaultDispatcher
with hierarchy #'clojure.core/global-hierarchy
and prefs {}.
The default value is :default.
It uses the method table methodical.impl.method_table.standard.StandardMethodTable.
These primary methods are known:
