Enum KnownCameraControl 

pub enum KnownCameraControl {
    Brightness,
    Contrast,
    Hue,
    Saturation,
    Sharpness,
    Gamma,
    WhiteBalance,
    BacklightComp,
    Gain,
    Pan,
    Tilt,
    Zoom,
    Exposure,
    Iris,
    Focus,
    Other(u128),
}

The list of known camera controls to the library.
These can control the picture brightness, etc.
Note that not all backends/devices support all these. Run supported_camera_controls() to see which ones can be set.

Other(u128)

Other camera control. Listed is the ID. Wasteful, however is needed for a unified API across Windows, Linux, and MacOSX due to Microsoft’s usage of GUIDs.

THIS SHOULD ONLY BE USED WHEN YOU KNOW THE PLATFORM THAT YOU ARE RUNNING ON.

Trait Implementations

impl Clone for KnownCameraControl

fn clone(&self) -> KnownCameraControl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KnownCameraControl

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

Formats the value using the given formatter.

impl Display for KnownCameraControl

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

Formats the value using the given formatter.

impl Hash for KnownCameraControl

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KnownCameraControl

fn cmp(&self, other: &KnownCameraControl) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KnownCameraControl

fn eq(&self, other: &KnownCameraControl) -> 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.

impl PartialOrd for KnownCameraControl

fn partial_cmp(&self, other: &KnownCameraControl) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
