Struct DeviceHandle 

pub struct DeviceHandle {
    pub adapter: Adapter,
    pub device: Device,
    pub queue: Queue,
    /* private fields */
}

An adapter and the device opened on it.

vello’s own DeviceHandle keeps adapter private, which is the only reason this type exists rather than being reused.

Fields

adapter: Adapter

device: Device

queue: Queue

Implementations

impl DeviceHandle

pub fn loss_monitor(&self) -> DeviceLossMonitor

Observe loss without replacing the context-owned callback.

pub fn adapter(&self) -> &Adapter

A method as well as a field, because vello’s handle offers one and call sites were written against it.

pub fn open_peer(&self) -> Option<(Device, Queue)>

The same driver’s device on a fresh instance of this adapter’s backend, with this device’s features and limits. Blocks while the device opens.

Not a second device on this adapter: Mesa’s CPU Vulkan driver compiles shaders for every device of one physical device one at a time, so work meant to run beside this device’s needs a physical device of its own.
