Struct IdleFade 

pub struct IdleFade { /* private fields */ }

The idle fade of a piece of chrome: when it was last woken, how long it then stays fully visible, and how long it takes to fade out.

Implementations

impl IdleFade

pub const fn new(hold: Duration, fade: Duration) -> IdleFade

Chrome that stays for hold after the last activity, then fades over fade. It starts hidden.

pub fn wake(&mut self, now: Instant)

Activity that shows the chrome happened at now.

pub fn hide(&mut self)

Hide the chrome at once (the person started something it would be in the way of).

pub fn is_idle(&self) -> bool

Whether nothing has woken the chrome since it was made or hidden.

pub fn opacity_at(&self, now: Instant, held: bool) -> f32

The chrome’s opacity at now; held keeps it fully visible.

pub fn fading_at(&self, now: Instant, held: bool) -> bool

Whether the chrome is fading at now, so its owner needs frames.

pub fn fade_deadline_at(&self, now: Instant, held: bool) -> Option<Instant>

When the fade starts, if it is still ahead at now: the owner’s next wake deadline.

pub fn fade_end(&self) -> Option<Instant>

When the fade will have run its course, if the chrome was woken.

pub fn finished_at(&self, now: Instant) -> bool

Whether the fade has run its course at now.

Trait Implementations

impl Clone for IdleFade

fn clone(&self) -> IdleFade

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdleFade

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

Formats the value using the given formatter.

impl PartialEq for IdleFade

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