Module persist 

The persister seam: a form’s write is a handler, resolved at boot from a string key on the descriptor.

Every form gets a [DefaultPersister] (the descriptor-driven single-statement insert/update) unless it names a registered Persister, letting an entity that needs a custom, atomic, multi-statement write (a tree’s ancestor closure, say) plug in without a hand-written CRUD handler. A persister is a registered domain write service, the same category as a picker source.

Structs

A registered persister: its dotted vendor.name key and the handler.

Enums

DeleteError

Why a delete failed.

SaveError

Why a persist failed.

Traits

Persister

Replaces the default insert/update for one form. An implementor owns its own transaction when the write is multi-statement. rec holds the validated submission plus anything the listeners added; rec.to_text_map() gives the all-text shape if that suits an implementation better.
