Struct AttentionConfig 

pub struct AttentionConfig {
    pub timeout: Duration,
    pub dim_margin: Duration,
    pub dim_ramp: Duration,
}

Timing policy. Held by value so a board can adjust it at runtime — the plumbing a future PROP_DISPLAY_TIMEOUT needs.

Fields

timeout: Duration

Inactivity before attention lapses.

dim_margin: Duration

How long before timeout an emissive panel dims as a warning. Zero (or anything at least as large as timeout) disables the dim state. Ignored for persistent panels.

dim_ramp: Duration

How long the fall from full brightness to the dim floor is drawn out over. Zero drops in a single step, which is what a persistent panel — and any board whose panel cannot be dimmed gradually — wants.

Implementations

impl AttentionConfig

pub const EMISSIVE: Self

OLED default: off after 30 s, dimmed for the last 10 s of that, falling into the dim over the first second of those ten.

The numbers are what a panel a person is actually reading from needs: twenty seconds is long enough to walk to a menu entry, read it, and think about it, and ten dimmed seconds afterwards is long enough that the warning is a warning rather than the last moment before the screen is gone.

pub const PERSISTENT: Self

E-paper default: menu returns home after 30 s. Longer than the emissive timeout because nothing is being spent to keep the screen readable — only stale menu context is at stake — and because each partial refresh is visible enough that a twitchy fallback would be an annoyance of its own.

Trait Implementations

impl Clone for AttentionConfig

fn clone(&self) -> AttentionConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttentionConfig

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

Formats the value using the given formatter.

impl PartialEq for AttentionConfig

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