Struct Camera

pub struct Camera {
    pub frame: State<Option<ImageHolder>>,
    pub info: State<Option<StreamInfo>>,
    pub error: State<Option<NokhwaError>>,
}

Available on crate feature camera only.

Expand description

Handle to a running camera. Closed when its owning scope is dropped.

Fields§

§frame: State<Option<ImageHolder>>

The latest frame produced by the camera.

§info: State<Option<StreamInfo>>

The resolution and frame rate negotiated with the device.

§error: State<Option<NokhwaError>>

The most recent error, if any.

Implementations§

§

impl Camera

pub fn create(config: CameraConfig) -> Camera

Open a camera and start streaming frames into reactive state.

Trait Implementations§

§

impl Clone for Camera

§

fn clone(&self) -> Camera

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

§

impl PartialEq for Camera

§

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

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

1.0.0 · Source§

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

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

§

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

§

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.

§

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.

§

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.

§

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.

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 §

impl<T> IntoEither for T

Source §

fn into_either(self, into_left: bool) -> Either<Self, Self>
