Enum AndonState 

pub enum AndonState {
    Normal,
    Warning {
        buffer_pct: u8,
    },
    TraceLoss {
        dropped_count: u64,
    },
}

Soft Andon state for visual trace loss indication (MacKenzie & Ware 1993).

Per MacKenzie & Ware (1993): “Input lag degrades human performance.” Hard blocking (AndonCord) creates lag; SoftAndon preserves responsiveness while making trace loss visually impossible to ignore.

Examples

use jugar_web::trace::AndonState;

let state = AndonState::Normal;
assert_eq!(state.overlay_color(), [0.0, 0.0, 0.0, 0.0]); // Invisible

let warning = AndonState::Warning { buffer_pct: 85 };
assert!(warning.overlay_color()[3] > 0.0); // Visible yellow

let loss = AndonState::TraceLoss { dropped_count: 10 };
assert!(loss.overlay_color()[3] > 0.0); // Visible red

Variants

Normal

Normal operation - all events being recorded.

Warning

Warning - buffer at 80%+ capacity.

Fields

buffer_pct: u8

Buffer fill percentage (80-99).

TraceLoss

Trace loss - events are being dropped.

Fields

dropped_count: u64

Number of frames dropped since last normal state.

Implementations

impl AndonState

pub const fn overlay_color(&self) -> [f32; 4]

Get HUD overlay color (Visual Management).

Returns RGBA color for drawing over the game canvas.

pub const fn status_text(&self) -> &'static str

Get status text for HUD display.

pub const fn is_error(&self) -> bool

Check if in error state (warning or trace loss).

pub const fn has_dropped(&self) -> bool

Check if any events have been dropped.

pub const fn dropped_count(&self) -> u64

Get number of dropped frames (0 if none).

Trait Implementations

impl Clone for AndonState

fn clone(&self) -> AndonState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AndonState

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

Formats the value using the given formatter.

impl Default for AndonState

fn default() -> AndonState

Returns the “default value” for a type.

impl PartialEq for AndonState

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