Struct UseEuvCamera 

pub struct UseEuvCamera {
    pub camera_open: Signal<bool>,
    pub camera_loading: Signal<bool>,
    pub error_message: Signal<String>,
    pub facing: Signal<EuvCameraFacing>,
    pub scan_result: Signal<String>,
    pub scan_handle: Signal<Option<IntervalHandle>>,
}

Reactive state for the camera, including camera control, facing mode, and QR code scanning results.

Fields

camera_open: Signal<bool>

Whether the camera stream is currently open.

camera_loading: Signal<bool>

Whether the camera is in the process of opening.

error_message: Signal<String>

The current error message, empty if no error.

facing: Signal<EuvCameraFacing>

The current camera facing direction (front or rear).

scan_result: Signal<String>

The last QR code scan result text.

scan_handle: Signal<Option<IntervalHandle>>

The interval handle for the periodic QR code scan timer.

Implementations

impl UseEuvCamera

Implementation of camera functionality.

pub fn use_camera_state() -> UseEuvCamera

Creates camera state for controlling camera stream and QR scanning.

Returns

• UseEuvCamera: The camera state.

pub fn on_close( self, config: Option<&EuvCameraConfig>, ) -> Option<Rc<dyn Fn(Event)>>

Creates a click event handler that closes the camera stream and stops the QR code scan.

Arguments

• Option<&EuvCameraConfig>: Optional camera configuration.

Returns

• Option<Rc<dyn Fn(Event)>>: A click event handler.

pub fn on_switch( self, config: Option<&EuvCameraConfig>, ) -> Option<Rc<dyn Fn(Event)>>

Creates a click event handler that switches the camera facing direction.

Arguments

• Option<&EuvCameraConfig>: Optional camera configuration.

Returns

• Option<Rc<dyn Fn(Event)>>: A click event handler.

pub fn on_open( self, config: Option<&EuvCameraConfig>, ) -> Option<Rc<dyn Fn(Event)>>

Creates a click event handler that opens the camera and starts QR scanning.

Arguments

• Option<&EuvCameraConfig>: Optional camera configuration.

Returns

• Option<Rc<dyn Fn(Event)>>: A click event handler.

pub fn cleanup(self, config: Option<&EuvCameraConfig>)

Registers a cleanup callback that closes the camera stream and stops the QR code scan timer when the component unmounts or the page route switches away.

Arguments

• Option<&EuvCameraConfig>: Optional camera configuration.

Trait Implementations

impl Clone for UseEuvCamera

fn clone(&self) -> UseEuvCamera

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UseEuvCamera

impl Debug for UseEuvCamera

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

Formats the value using the given formatter.

impl Eq for UseEuvCamera

impl PartialEq for UseEuvCamera

fn eq(&self, other: &UseEuvCamera) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
