Struct screen_13::driver::device::DeviceInfo

pub struct DeviceInfo {
    pub debug: bool,
    pub select_physical_device: Box<SelectPhysicalDeviceFn>,
}

Information used to create a Device instance.

Fields

debug: bool

Enables Vulkan validation layers.

This requires a Vulkan SDK installation and will cause validation errors to introduce panics as they happen.

NOTE: Consider turning OFF debug if you discover an unknown issue. Often the validation layers will throw an error before other layers can provide additional context such as the API dump info or other messages. You might find the “actual” issue is detailed in those subsequent details.

Platform-specific

macOS: Has no effect.

select_physical_device: Box<SelectPhysicalDeviceFn>

Callback function used to select a PhysicalDevice from the available devices. The callback must return the index of the selected device.

Implementations

impl DeviceInfo

pub fn new() -> DeviceInfoBuilder

Specifies default device information.

pub fn integrated_gpu(physical_devices: &[PhysicalDevice]) -> usize

A builtin DeviceInfo::select_physical_device function which prioritizes selection of lower-power integrated GPU devices.

pub fn discrete_gpu(physical_devices: &[PhysicalDevice]) -> usize

A builtin DeviceInfo::select_physical_device function which prioritizes selection of higher-performance discrete GPU devices.

Trait Implementations

impl From<DeviceInfoBuilder> for DeviceInfo

fn from(info: DeviceInfoBuilder) -> Self

Converts to this type from the input type.
