Enum Device

pub enum Device<'a> {
    Custom(Box<dyn DeviceTrait<'a, Stream = Stream<'a>> + Send + 'a>),
    V4l2(Handle),
}

Platform device

Leaky abstraction: if you require access to platform specific features, match the enum instance to get the underlying HAL implementation.

A device is used to read/write control properties, start video streams and more.

Variants

Custom(Box<dyn DeviceTrait<'a, Stream = Stream<'a>> + Send + 'a>)

Can be used to wrap your own struct

V4l2(Handle)

Video4Linux2 device handle

Trait Implementations

impl<'a> Device<'a> for Device<'a>

type Stream = Stream<'a>

Capture stream type created by this device

fn streams(&self) -> Result<Vec<StreamDescriptor>>

Returns the supported streams

fn controls(&self) -> Result<Vec<Descriptor>>

Returns the supported controls

fn control(&self, id: u32) -> Result<State>

Returns the current control value for an ID

fn set_control(&mut self, id: u32, val: &State) -> Result<()>

Sets the control value, returns error for incompatible value types

fn start_stream(&self, desc: &StreamDescriptor) -> Result<Self::Stream>

Returns a stream which produces images
