Struct KeepAwakeGuard 

pub struct KeepAwakeGuard {
    active: bool,
}

RAII guard that holds the keep-awake assertion while alive.

Construct via KeepAwakeGuard::new; drop to release.

Fields

active: bool

true once the OS assertion has been claimed. false after release. Drop-of-released is a no-op so release can be called explicitly.

Implementations

impl KeepAwakeGuard

pub fn new() -> Self

Acquire a new keep-awake assertion. The real OS impl will fail if the assertion can’t be created (rare); the stub today always succeeds.

pub fn release(&mut self)

Release the assertion explicitly (before Drop). Idempotent — repeated calls are safe.

Trait Implementations

impl Debug for KeepAwakeGuard

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

Formats the value using the given formatter.

impl Default for KeepAwakeGuard

fn default() -> Self

Returns the “default value” for a type.

impl Drop for KeepAwakeGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
