Struct realsense_rust::context::Context

pub struct Context { /* fields omitted */ }

Type describing a RealSense context, used by the rest of the API.

Implementations

impl Context

pub fn new() -> Result<Self, ContextConstructionError>

Construct a new context.

Errors

Returns ContextConstructionError if the context cannot be created.

pub fn create_device_hub(&self) -> Result<DeviceHub, CouldNotGetDeviceHubError>

Creates a device hub from the context.

Errors

Returns CouldNotGetDeviceHubError if the device hub cannot be created.

pub fn query_devices(
    &self,
    product_mask: HashSet<Rs2ProductLine>
) -> Vec<Device>

Get a list of devices that are already connected to the host.

pub fn add_device<P>(&mut self, file: P) -> Result<Device> where
    P: AsRef<Path>, 

Create a new device and add it to the context.

This adds a “device” at a particular file on the system to the RealSense context. Returns a handle to the device, or an error if this call fails.

Errors

Returns NulError if the provided file path cannot be cleanly represented as a CString. This usually only occurs if you have null characters in the path. Constructing a path using the utilties in Rust’s std::fs are expected to work.

Returns CouldNotAddDeviceError if the device cannot be added.

pub fn remove_device<P>(&mut self, file: P) -> Result<()> where
    P: AsRef<Path>, 

Removes a playback device from the context, if it exists

This removes a “device” at a particular file on the system from the RealSense context. Returns nothing (null tuple) or an Error if the device cannot be removed.

Errors

Returns CouldNotRemoveDeviceError if the device cannot be removed for any reason.
