Struct MetroBranch 

pub struct MetroBranch {
    pub id: String,
    pub label: String,
    pub kind: StationKind,
    pub lit: bool,
}

One caller arm diverging off a trunk station (in practice the gRPC stop): a marked client (UI viz vs CLI) that invokes the verb. The renderer draws it as a branch leaving the fork point at an angle, distinct from the linear trunk.

Fields

id: String

Stable id (e.g. caller::ui::Ops.RunTestMatrix). Selection identity.

label: String

Short human label drawn on the arm (e.g. the client/binary name).

kind: StationKind

The arm kind — UiClient or CliClient (carries the UI/CLI marker).

lit: bool

true = the verb was exercised through THIS client in the latest coverage run (a LIT arm). false = not yet proven through this client (unlit) — honest, never a trunk-red (arms don’t gate).

Implementations

impl MetroBranch

pub fn new( id: impl Into<String>, label: impl Into<String>, kind: StationKind, lit: bool, ) -> Self

Construct a caller arm. The kind should be a client-arm kind (UiClient/CliClient); the marker is derived from it.

pub fn marker(&self) -> Option<&'static str>

The arm’s caller marker (UI/CLI), or None if a non-client kind was (mis)used.
