Struct FormRegistry 

pub struct FormRegistry { /* private fields */ }

A lightweight, opt-in registry that connects app-owned Model<T> values to a FormState.

Notes:

• This is intentionally app-owned state (store it in your window state/driver), not a model.
• Validation remains value-driven: callers provide validate(&T) -> Option<Arc<str>>.
• The registry only reads values from the ModelStore; it never owns field values.

Implementations

impl FormRegistry

pub fn new() -> Self

pub fn options(self, options: FormRegistryOptions) -> Self

pub fn field_ids(&self) -> impl Iterator<Item = &FormFieldId>

pub fn register_into_form_state<H: ModelHost>( &self, host: &mut H, form_state: &Model<FormState>, )

pub fn register_field<T>( &mut self, id: impl Into<FormFieldId>, model: impl IntoFormValueModel<T>, initial: T, validate: impl Fn(&T) -> Option<Arc<str>> + 'static, )

where T: Clone + PartialEq + 'static,

pub fn handle_model_changes<H: ModelHost>( &self, host: &mut H, form_state: &Model<FormState>, changed: &[ModelId], )

pub fn submit<H: ModelHost>( &self, host: &mut H, form_state: &Model<FormState>, ) -> bool

pub fn submit_action_host( &self, host: &mut dyn UiActionHost, form_state: &Model<FormState>, ) -> bool

Object-safe form submission helper for action hooks.

fret_ui::action callbacks receive a &mut dyn UiActionHost (object-safe by design), while submit() is generic over ModelHost. This helper bridges that gap without exposing FormRegistry internals to call sites.

Trait Implementations

fn clone(&self) -> FormRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FormRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FormRegistry

fn default() -> FormRegistry

Returns the “default value” for a type.
