Enum PowerPreference

#[repr(C)]
pub enum PowerPreference {
    Default = 0,
    LowPower = 1,
    HighPerformance = 2,
}

Power Preference when choosing a physical adapter.

Variants

Default = 0

Prefer low power when on battery, high performance when on mains.

LowPower = 1

Adapter that uses the least possible power. This is often an integerated GPU.

HighPerformance = 2

Adapter that has the highest performance. This is often a discrete GPU.

Trait Implementations

impl Clone for PowerPreference

fn clone(&self) -> PowerPreference

Returns a copy 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 Hash for PowerPreference

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

where __H: Hasher,

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 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.
