Struct A11yBuilder 

pub struct A11yBuilder { /* private fields */ }

The annotations .a11y(|a| …) collects (docs/accessibility.md). The three strings are TextSources, so each takes a literal, a String, a Signal<String> or a closure: a gauge’s value follows the gauge, and a localized label follows the locale.

Implementations

impl A11yBuilder

pub fn label<M>(self, s: impl IntoText<M>) -> Self

What the screen reader calls the element.

pub fn hint<M>(self, s: impl IntoText<M>) -> Self

A longer description of what the element does.

pub fn value<M>(self, s: impl IntoText<M>) -> Self

The control’s current value read aloud by the screen reader (e.g. a Meter’s “72%”). Reactive like the others: .value(move || format!("{:.0}%", level.get())) re-sends the value whenever level changes.

pub fn role(self, r: Role) -> Self

pub fn selected<M>(self, on: impl IntoReactive<bool, M>) -> Self

Whether this element is the selected one among its peers (a Role::Tab, a row): the platform’s selected state, which a screen reader reads as “selected”. Reactive like the strings: .selected(move || current.get() == key) re-sends it when the selection moves.

pub fn hidden(self) -> Self

Hide this element from assistive tech (still visible on screen), e.g. a redundant chrome element already announced by its labeled sibling.

pub fn decorative(self) -> Self

Purely decorative (a background flourish): hidden from assistive tech and, for images, exempt from the “needs a label” lint (§13).
