Struct BarcodeScannerEffects 

Source 
pub struct BarcodeScannerEffects<'a, 'b, S: AppState> { /* private fields */ }
Expand description

Convenience builder for standard barcode scanner host capabilities.

Implementations§

Source§

impl<'a, 'b, S: AppState> BarcodeScannerEffects<'a, 'b, S>

Source

pub fn scan(self, request: BarcodeScanRequest) -> EffectBuilder<'a, 'b, S>

Starts a live barcode scanning session.

request.formats should list only formats the product accepts. The host may open a camera UI, display prompt, and return one or more decoded barcode values depending on allow_multiple.

Source

pub fn decode_image( self, request: BarcodeImageDecodeRequest, ) -> EffectBuilder<'a, 'b, S>

Decodes barcode data from image bytes supplied by the app.

Use this when the image already exists, such as a file import or camera frame captured elsewhere. The host should not request camera permission for this operation unless its decoder specifically requires it.

Source

pub fn cancel_scan(self) -> EffectBuilder<'a, 'b, S>

Cancels the active live barcode scanning session.

Use this when the user leaves the scanning screen or chooses another input path. Hosts may treat cancellation of a non-running session as success.

impl<T> Downcast for T
where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
Source§

impl<T> From<T> for T

Source§

fn from(t: T) -> T

Returns the argument unchanged.

Source§

impl<T, U> Into<U> for T

Source§

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Source§

The type returned in the event of a conversion error.
Source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
