Struct FieldControlOptions 

pub struct FieldControlOptions { /* private fields */ }

Everything a field-aware control tells FieldMeta::attributes_for about itself.

Overrides are resolved before any attribute is built, so an overridden state is never emitted twice and never has to be filtered back out of the result.

let options = FieldControlOptions::new()
    .required(Some(true))
    .name(Some(Rc::from("terms")))
    .surface(FieldSurface::BUTTON_WIDGET);

Implementations

impl FieldControlOptions

pub fn new() -> Self

Creates options that override nothing and render onto FieldSurface::NATIVE.

pub fn state(self, state: FieldStateOverrides) -> Self

Replaces the whole state override set.

pub fn invalid(self, invalid: Option<bool>) -> Self

Overrides the metadata’s invalid state.

pub fn disabled(self, disabled: Option<bool>) -> Self

Overrides the metadata’s disabled state.

pub fn required(self, required: Option<bool>) -> Self

Overrides the metadata’s required state.

pub fn id(self, id: Option<Rc<str>>) -> Self

Overrides the metadata’s control id.

This replaces the emitted value; it does not suppress the attribute. id is a global attribute, so there is no element that must not carry one.

pub fn name(self, name: Option<Rc<str>>) -> Self

Overrides the metadata’s control name.

This replaces the emitted value. To suppress the attribute on an element that cannot carry it, set FieldSurface::name to NameSurface::Omit instead.

pub fn surface(self, surface: FieldSurface) -> Self

Declares how the rendered element spells each field attribute.
