Struct CouplingItem 

pub struct CouplingItem {
    pub key: String,
    pub kind: String,
    pub name: String,
    pub path: Option<String>,
    pub fan_in: u32,
    pub fan_out: u32,
    pub total: u32,
    pub instability: f64,
}

One node’s directed call coupling in a CouplingReport.

Fields

key: String

Natural key of the node.

kind: String

Kind token (e.g. fn).

name: String

Human-facing name.

path: Option<String>

Repository-relative path, if any.

fan_in: u32

How many distinct other nodes call this one.

fan_out: u32

How many distinct other nodes this one calls.

total: u32

fan_in + fan_out — the directed equivalent of the undirected degree.

instability: f64

Martin’s instability, fan_out / (fan_in + fan_out), rounded to two decimals. 0.0 = purely depended-on (stable); 1.0 = purely depending (unstable). The denominator is never zero: an item exists only when it has at least one non-self call edge.
