Opens one-shot Postgrex connections from a Lantern.Source.
Lantern deliberately avoids a long-lived pool: an embeddable live_component
has no reliable teardown hook, so each operation opens a connection, runs, and
closes it. The per-call cost is irrelevant for an administrative tool and it
leaves nothing for host applications to supervise.
Summary
Functions
Resolves source_input to a Source, opens a connection, and runs fun.
Functions
@spec run(Lantern.Source.t() | String.t() | keyword() | map(), (pid() -> result)) :: result | {:error, String.t()} when result: term()
Resolves source_input to a Source, opens a connection, and runs fun.
fun receives the Postgrex connection pid and its result is returned as-is.
Connection/resolution failures return {:error, reason}.
