Enum PowerPreference 

pub enum PowerPreference {
    None,
    LowPower,
    HighPerformance,
}

GPU power preference for adapter selection

Controls which GPU adapter is preferred when multiple GPUs are available (e.g., integrated Intel GPU vs discrete NVIDIA/AMD GPU).

Variants

None

No preference - let the system decide (default)

LowPower

Prefer integrated GPU (Intel/AMD iGPU) - saves battery

HighPerformance

Prefer discrete GPU (NVIDIA/AMD) - maximum performance

Implementations

impl PowerPreference

pub fn to_wgpu(self) -> PowerPreference

Convert to wgpu::PowerPreference

pub fn display_name(&self) -> &'static str

Display name for UI

pub fn all() -> &'static [PowerPreference]

All available power preferences for UI iteration

Trait Implementations

impl Clone for PowerPreference

fn clone(&self) -> PowerPreference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PowerPreference

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

Formats the value using the given formatter.

impl Default for PowerPreference

fn default() -> PowerPreference

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PowerPreference

fn deserialize<__D>( __deserializer: __D, ) -> Result<PowerPreference, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PowerPreference

fn eq(&self, other: &PowerPreference) -> 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 Serialize for PowerPreference

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PowerPreference

impl Eq for PowerPreference
