Enum nokhwa::utils::ApiBackend

pub enum ApiBackend {

}

The list of known capture backends to the library.

• AUTO is special - it tells the Camera struct to automatically choose a backend most suited for the current platform.
• AVFoundation - Uses AVFoundation on MacOSX
• Video4Linux - Video4Linux2, a linux specific backend.
• UniversalVideoClass - DEPRECATED Universal Video Class (please check libuvc). Platform agnostic, although on linux it needs sudo permissions or similar to use.
• MediaFoundation - Microsoft Media Foundation, Windows only,
• OpenCv - Uses OpenCV to capture. Platform agnostic.
• GStreamer - DEPRECATED Uses GStreamer RTP to capture. Platform agnostic.
• Network - Uses OpenCV to capture from an IP.
• Browser - Uses browser APIs to capture from a webcam.

Trait Implementations

impl Clone for ApiBackend

fn clone(&self) -> ApiBackend

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ApiBackend

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ApiBackend

fn deserialize<__D>( __deserializer: __D ) -> Result<ApiBackend, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ApiBackend

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

Formats the value using the given formatter.

impl Hash for ApiBackend

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 ApiBackend

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ApiBackend> for ApiBackend

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<ApiBackend> for ApiBackend

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for ApiBackend

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ApiBackend

impl Eq for ApiBackend

impl StructuralEq for ApiBackend
