Struct SemanticsSetProgress 

pub struct SemanticsSetProgress { /* private fields */ }

What a control does when a screen reader moves its value, e.g. a VoiceOver swipe up or a TalkBack set-progress action.

This is Compose’s SemanticsActions.SetProgress. The value comes in the control’s own range, and the answer says whether the control took it.

Implementations

impl SemanticsSetProgress

pub fn new(handler: impl Fn(f32) -> bool + 'static) -> SemanticsSetProgress

pub fn invoke(&self, value: f32) -> bool

Trait Implementations

impl Clone for SemanticsSetProgress

fn clone(&self) -> SemanticsSetProgress

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SemanticsSetProgress

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for SemanticsSetProgress

impl PartialEq for SemanticsSetProgress

Two set-progress actions always read as the same action, for the reason SemanticsCustomAction’s own comparison gives: the closure is rebuilt on every semantics collection, so comparing handler identity would report a changed tree on every frame.

fn eq(&self, _other: &SemanticsSetProgress) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
