Struct FieldError 

pub struct FieldError { /* private fields */ }

HeroUI FieldError — validation-driven error text.

Unlike ErrorMessage, a FieldError manages its own visibility from the validation state: it renders nothing unless the field is invalid and a message is present.

Implementations

impl FieldError

pub fn new() -> Self

Creates an empty field error.

pub fn message(self, text: impl Into<SharedString>) -> Self

The validation message. Setting a message also marks the field invalid, matching React Aria’s ValidationResult behaviour.

pub fn is_invalid(self, v: bool) -> Self

Overrides visibility independently of the message.

pub fn id(self, id: impl Into<ElementId>) -> Self

Supplies the stable element identity needed for the v3 height/opacity transition when a standalone FieldError is toggled across renders.

Trait Implementations

impl Default for FieldError

fn default() -> Self

Returns the “default value” for a type.

impl IntoElement for FieldError

type Element = ViewElement<FieldError>

The specific type of element into which the implementing type is converted. Useful for converting other types into elements automatically, like Strings

fn into_element(self) -> Self::Element

Convert self into a type that implements Element.

fn into_any_element(self) -> AnyElement

Convert self into a dynamically-typed AnyElement.

impl RenderOnce for FieldError

fn render(self, window: &mut Window, cx: &mut App) -> impl IntoElement

Render this component into an element tree. Note that this method takes ownership of self, as compared to Render::render() method which takes a mutable reference.
