Struct DeviceInfo 

pub struct DeviceInfo {
    pub debug: bool,
    pub physical_device_index: usize,
}

Information used to create a Device instance.

Fields

debug: bool

Enables the Vulkan validation layers.

This requires a Vulkan SDK installation and will panic when validation errors happen. See the LunarG Vulkan Validation Layers documentation for setup and behavior details.

When stderr is attached to an interactive terminal, validation errors will park the callback thread for debugger attach.

NOTE: Consider turning OFF debug if you discover an unknown issue. Often the validation layers will report 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 unless the loaded feature is enabled.

physical_device_index: usize

Index of the PhysicalDevice from the available devices. See Instance::physical_devices.

Implementations

impl DeviceInfo

pub fn builder() -> DeviceInfoBuilder

Creates a default DeviceInfoBuilder.

pub fn into_builder(self) -> DeviceInfoBuilder

Converts a DeviceInfo into a DeviceInfoBuilder.

Trait Implementations

impl Clone for DeviceInfo

fn clone(&self) -> DeviceInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DeviceInfo

impl Debug for DeviceInfo

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

Formats the value using the given formatter.

impl Default for DeviceInfo

fn default() -> DeviceInfo

Returns the “default value” for a type.

impl Eq for DeviceInfo

impl From<DeviceInfoBuilder> for DeviceInfo

fn from(info: DeviceInfoBuilder) -> Self

Converts to this type from the input type.

impl Hash for DeviceInfo

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DeviceInfo

fn eq(&self, other: &DeviceInfo) -> 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.
