Struct CameraEffects 

pub struct CameraEffects<'a, 'b, S: AppState> { /* private fields */ }

Convenience builder for standard camera host capabilities.

Implementations

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

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

Queries camera permission and available camera devices.

Use this before showing camera-specific controls. The result contains the current permission state and host-visible devices, including facing direction and flashlight availability where known.

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

Requests camera permission from the host.

request.reason can carry product-facing context for hosts that support a pre-prompt or custom rationale. The success action receives the resulting CameraPermission state.

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

Captures a still photo through the selected host camera.

request chooses camera id or facing direction, optional resolution, image format, flash behavior, and quality. The success action receives image bytes plus dimensions and content type.

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

Enables, disables, or adjusts the camera flashlight where supported.

request.camera_id selects the device, enabled chooses the desired state, and intensity optionally requests a platform-specific brightness level from 0 to 100. Many desktop cameras have no torch.

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

Cancels an active camera capture session.

Use this when the user dismisses the camera flow before a photo is returned. Hosts may return success when there is no active capture.
