Struct ascom_alpaca::api::Devices

pub struct Devices { /* private fields */ }

Devices collection.

This data structure holds devices of arbitrary categories (cameras, telescopes, etc.) and allows to register and access them by their kind and index.

Implementations

impl Devices

pub fn register<DynTrait: ?Sized>( &mut self, device: impl RegistrableDevice<DynTrait> )

Register a device in the storage.

device can be an instance of any of the category traits (Camera, Telescope, etc.).

pub fn get<DynTrait: ?Sized + RetrieavableDevice>( &self, device_number: usize ) -> Option<&DynTrait>

Retrieve a device by its category trait and an index within that category.

Example: devices.get::<dyn Camera>(0) returns the first camera in the storage.

impl Devices

pub fn iter<DynTrait: ?Sized + RetrieavableDevice>( &self ) -> impl '_ + Iterator<Item = Arc<DynTrait>>

Iterate over all devices of a given type.

pub fn iter_all(&self) -> impl '_ + Iterator<Item = (TypedDevice, usize)>

Iterate over all registered devices.

The second element of the tuple is the index of the device within its category (not the whole collection).

Trait Implementations

impl Debug for Devices

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

Formats the value using the given formatter.

impl Default for Devices

fn default() -> Devices

Returns the “default value” for a type.

impl Extend<TypedDevice> for Devices

fn extend<T: IntoIterator<Item = TypedDevice>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl FromIterator<TypedDevice> for Devices

fn from_iter<T: IntoIterator<Item = TypedDevice>>(iter: T) -> Self

Creates a value from an iterator.
