Struct MetroLine 

pub struct MetroLine {
    pub id: String,
    pub label: String,
    pub stations: Vec<MetroStation>,
}

One metro line — a single test chain, button → … → warehouse.

Fields

id: String

Stable id (the chain id, e.g. bench_run→Bench.Submit).

label: String

Human label drawn at the head of the line.

stations: Vec<MetroStation>

Stops in chain order: START first, TERMINUS last (by convention).

Implementations

impl MetroLine

pub fn new( id: impl Into<String>, label: impl Into<String>, stations: Vec<MetroStation>, ) -> Self

pub fn is_green(&self) -> bool

The green verdict. A line is green only when every gating station (Start / Emitter / Grpc / Terminus) is lit. Pass-throughs are ignored — they are ridden through, not lit, and never make a line red. A line with no gating stations is vacuously green.

pub fn unlit(&self) -> Vec<&MetroStation>

The gating stations that are unlit — the reason a line is red. Empty when is_green.

pub fn station_count(&self) -> usize

Count of full stations (everything but pass-through ticks).
