Enum Level

#[repr(i32)]
pub enum Level {
    Partial = 1,
    Full = 26,
    ScreenBright = 10,
    ScreenDim = 6,
}

Possible levels for a wake lock.

Variants

Partial = 1

Ensures that the CPU is running; the screen and keyboard backlight will be allowed to go off.

If the user presses the power button, then the screen will be turned off but the CPU will be kept on until all partial wake locks have been released.

Full = 26

👎Deprecated

Ensures that the screen and keyboard backlight are on at full brightness.

If the user presses the power button, then the wake lock will be implicitly released by the system, causing both the screen and the CPU to be turned off. Contrast with Level::Partial.

Deprecation

This constant was deprecated in API level 17. Most applications should use WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON instead of this type of wake lock, as it will be correctly managed by the platform as the user moves between applications and doesn’t require a special permission.

ScreenBright = 10

👎Deprecated

Ensures that the screen is on at full brightness; the keyboard backlight will be allowed to go off.

If the user presses the power button, then the wake lock will be implicitly released by the system, causing both the screen and the CPU to be turned off. Contrast with Level::Partial.

Deprecation

This constant was deprecated in API level 15. Most applications should use WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON instead of this type of wake lock, as it will be correctly managed by the platform as the user moves between applications and doesn’t require a special permission.

ScreenDim = 6

👎Deprecated

Wake lock level: Ensures that the screen is on (but may be dimmed); the keyboard backlight will be allowed to go off.

If the user presses the power button, then the wake lock will be implicitly released by the system, causing both the screen and the CPU to be turned off. Contrast with Level::Partial.

Deprecation

This constant was deprecated in API level 17. Most applications should use WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON instead of this type of wake lock, as it will be correctly managed by the platform as the user moves between applications and doesn’t require a special permission.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl Hash for Level

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 Level

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