Enum CouplingOrder 

pub enum CouplingOrder {
    Total,
    FanIn,
    FanOut,
}

How a CouplingReport’s items are ranked. The three orders answer three different questions, which a single undirected degree cannot tell apart.

Variants

Total

By fan_in + fan_out — overall call coupling.

FanIn

By fan_in — the most depended-on symbols (“what calls this?”).

FanOut

By fan_out — the symbols that reach furthest (“what does this call?”).

Implementations

impl CouplingOrder

pub fn as_str(self) -> &'static str

The stable token for this order, as accepted by from_token.

pub fn from_token(s: &str) -> Option<Self>

Parse an order token. None for anything else — callers surface an error rather than silently ranking by something the caller did not ask for.

pub fn tokens() -> [&'static str; 3]

The tokens from_token accepts, for error messages and argument schemas — so the accepted set is stated in exactly one place.
