A form-ready struct holding Peri validation results.
Peri.Phoenix.to_form/3 builds this struct from a schema and raw params,
and the Phoenix.HTML.FormData implementation (available when
phoenix_html is loaded) converts it into a Phoenix.HTML.Form, so
Peri schemas plug into Phoenix.Component.form/1 and <.input> without
Ecto.
Fields
:schema- the Peri schema the params were validated against:data- the validated data (atom keys),%{}when validation failed:params- the raw params as received (usually string keys):errors- errors in changeset format,%{field => [{message, opts}]}with nested humanized maps under assoc keys (list entries keyed by index):name- the form name, defaults to"peri":action- the form action (:validate,:save, ...), used by LiveView to decide when to show errors
