Struct KdeExternalBrightnessDeviceV1

pub struct KdeExternalBrightnessDeviceV1 { /* private fields */ }

brightness control device

After creating this object, the client should issue all relevant setup requests (set_internal, set_edid, set_max_brightness, optionally set_observed_brightness) and finish the sequence with commit. Afterwards, for each change in values, the client must call commit again.

See also the Request enum for this interface.

Implementations

impl KdeExternalBrightnessDeviceV1

pub fn requested_brightness(&self, value: u32)

requests the client to change the brightness to this value

The client must ensure that if the brightness level changes due to external factors, that it either overwrites those changes with what the compositor last requested, or commit again with set_observed_brightness specifying the changed brightness.

Trait Implementations

impl Borrow<ObjectId> for KdeExternalBrightnessDeviceV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for KdeExternalBrightnessDeviceV1

fn clone(&self) -> KdeExternalBrightnessDeviceV1

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KdeExternalBrightnessDeviceV1

impl PartialEq<Weak<KdeExternalBrightnessDeviceV1>> for KdeExternalBrightnessDeviceV1

fn eq(&self, other: &Weak<KdeExternalBrightnessDeviceV1>) -> 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.
