Struct UseDevices 

pub struct UseDevices {
    pub devices: Signal<Vec<Device>>,
    pub ready: Signal<bool>,
    pub refresh: Callback<()>,
}

Handle returned by use_devices.

Fields

devices: Signal<Vec<Device>>

The current list of cameras reported by cameras::devices.

Updated asynchronously by refresh, the UI thread is never blocked by platform device enumeration.

ready: Signal<bool>

Flips from false to true once the first refresh completes.

Lets the UI distinguish “we haven’t scanned yet” (show a loading state) from “we scanned and found no cameras” (show an empty state). Remains true for the rest of the component’s lifetime.

refresh: Callback<()>

Callback that rescans the platform for cameras and updates devices.

Runs cameras::devices() on a worker thread. Errors are swallowed; the signal stays at its previous value.

Trait Implementations

impl Clone for UseDevices

fn clone(&self) -> UseDevices

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for UseDevices

fn eq(&self, other: &UseDevices) -> 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 Copy for UseDevices
