Enum BackendPreference 

pub enum BackendPreference {
    VulkanPreferred,
    OpenGLPreferred,
    PlatformDefault,
    Specific(Backends),
}

Backend preference for GPU initialisation.

agpu is Vulkan-first: when VulkanPreferred is used (the default), the engine tries the Vulkan backend before falling back to the platform default. OpenGLPreferred selects GL/GLES first.

Variants

VulkanPreferred

Try Vulkan first, then fall back to the platform default.

OpenGLPreferred

Try OpenGL/GLES first, then fall back to the platform default.

PlatformDefault

Use the platform default (DX12 on Windows, Metal on macOS, Vulkan on Linux).

Specific(Backends)

Force a specific set of backends.

Implementations

impl BackendPreference

pub fn to_backends(self) -> Backends

Convert to the concrete wgpu::Backends bitflags.

PlatformDefault selects the native API for the current OS: DX12 on Windows, Metal on macOS, Vulkan elsewhere.

Trait Implementations

impl Clone for BackendPreference

fn clone(&self) -> BackendPreference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendPreference

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

Formats the value using the given formatter.

impl Default for BackendPreference

fn default() -> BackendPreference

Returns the “default value” for a type.

impl PartialEq for BackendPreference

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