Struct TextFieldView 

pub struct TextFieldView<State: 'static> { /* private fields */ }

A declarative M3 text field. See the module docs.

Implementations

impl<State: 'static> TextFieldView<State>

pub fn label(self, label: impl Into<String>) -> Self

Set the floating label (see the module docs’ Floating label).

pub fn supporting_text(self, text: impl Into<String>) -> Self

Set the helper line below the field. An error_text always replaces it.

pub fn error_text(self, text: impl Into<String>) -> Self

Put the field in its error state: the indicator/outline, the floated label and the supporting line all recolor to error, and this text replaces supporting_text.

pub fn leading(self, view: impl View<State>) -> Self

Mount a leading view in a ICON_SIZE slot at the field’s start edge. The slot’s content owns its own ink and size; the field only reserves and positions the slot.

pub fn trailing(self, view: impl View<State>) -> Self

Mount a trailing view in a ICON_SIZE slot at the field’s end edge — see leading.

pub fn variant(self, variant: TextFieldVariant) -> Self

Choose the container treatment (default TextFieldVariant::Filled).

pub fn obscured(self, obscured: bool) -> Self

Mask the rendered glyphs (the baseline field’s obscured mode, which also publishes the secret IME hint).

pub fn enabled(self, enabled: bool) -> Self

Set whether the field accepts input (default true). A disabled field refuses focus and dims both the baseline’s content and this widget’s chrome.

pub fn on_submit<F: Fn(&mut State, String) + 'static>( self, on_submit: F, ) -> Self

Set the Enter handler (the baseline field’s on_submit).

Trait Implementations

impl<State: 'static> View<State> for TextFieldView<State>

type Element = TextFieldWidget

The retained widget this view produces.

fn build(&self, ctx: &mut BuildCtx<'_>) -> TextFieldWidget

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &Self, element: &mut TextFieldWidget, ctx: &mut BuildCtx<'_>, ) -> ChangeFlags

Reconcile prev (the previous view of the same type) against the live element, mutating it in place and reporting what changed.

fn teardown(&self, element: &mut TextFieldWidget, ctx: &mut BuildCtx<'_>)

Tear down element when this view is being removed.

fn message(&self, _element: &mut Self::Element, _state: &mut State)

Deliver an event message to this view, mutating application state.
