Struct FieldMeta 

pub struct FieldMeta { /* private fields */ }

Signal-backed presentation metadata for one field-shaped value.

The flag meanings are producer-defined. This type does not track an initial value or classify validity. Error strings are already formatted for display before they cross this boundary.

Implementations

impl FieldMeta

pub fn id(&self) -> Option<Rc<str>>

Returns the rendered control id.

pub fn set_id(&mut self, id: Option<Rc<str>>)

Replaces the rendered control id.

pub fn name(&self) -> Option<Rc<str>>

Returns the rendered control name.

pub fn set_name(&mut self, name: Option<Rc<str>>)

Replaces the rendered control name.

pub fn required(&self) -> bool

Returns whether the field is required.

pub fn set_required(&mut self, required: bool)

Replaces the producer-defined required state.

pub fn disabled(&self) -> bool

Returns whether the field is disabled.

pub fn set_disabled(&mut self, disabled: bool)

Replaces the producer-defined disabled state.

pub fn invalid(&self) -> bool

Returns whether the field is invalid.

An explicit invalid state wins; otherwise invalidity is derived from whether errors exist.

pub fn set_invalid(&mut self, invalid: Option<bool>)

Sets an explicit invalid state, or restores error-derived invalidity with None.

pub fn errors(&self) -> Vec<Rc<str>>

Returns the pre-rendered error text.

pub fn set_errors(&mut self, errors: Vec<Rc<str>>)

Replaces the pre-rendered error text.

pub fn touched(&self) -> bool

Returns whether the field is touched.

pub fn set_touched(&mut self, touched: bool)

Replaces the producer-defined touched state.

pub fn dirty(&self) -> bool

Returns whether the field is dirty.

pub fn set_dirty(&mut self, dirty: bool)

Replaces the producer-defined dirty state.

pub fn register_description_id( &mut self, id: Rc<str>, ) -> FieldMetaIdRegistration

Registers a description element id until the returned registration is dropped.

pub fn register_error_id(&mut self, id: Rc<str>) -> FieldMetaIdRegistration

Registers an error element id until the returned registration is dropped.

pub fn attributes(&self) -> Vec<Attribute>

Returns attributes for a rendered control using the metadata’s flag states.

pub fn attributes_with(&self, overrides: FieldMetaOverrides) -> Vec<Attribute>

Returns attributes for a rendered control, applying per-flag explicit overrides.

pub fn set_values(&mut self, values: FieldMetaValues)

Replaces producer-owned metadata values without disturbing registered part ids.
