Struct AttributeSpec 

pub struct AttributeSpec {
    pub value_type: ValueType,
    pub label: Option<String>,
    pub name: Option<String>,
    pub short: Option<String>,
    pub description: Option<String>,
    pub formula: Option<String>,
    pub calc: Option<String>,
    pub direction: Direction,
    pub abbreviate: Option<bool>,
    pub group: Option<String>,
    pub thresholds: Option<Thresholds>,
    pub omit_at: f64,
}

Describes one attribute key (on a node or an edge). Everything the UI needs to label, explain, format, compute and threshold the metric — so the viewer hardcodes no metric by name.

Fields

value_type: ValueType

label: Option<String>

Concise display label (table grouping, popup rows).

name: Option<String>

Full name used as a tooltip title (falls back to label).

short: Option<String>

Short label for narrow table headers (falls back to label).

description: Option<String>

Long human description (tooltip body).

formula: Option<String>

Human-readable formula, e.g. "sloc × (fan_in × fan_out)²" (display only).

calc: Option<String>

Evaluable JS expression over sibling attribute names + Math, e.g. "sloc * (fan_in * fan_out) ** 2". Lets the UI show the live derivation.

direction: Direction

Whether higher or lower is “better” — drives delta colouring. Neutral (the default) is omitted from the wire.

abbreviate: Option<bool>

Format large values with K/M suffixes.

group: Option<String>

Optional group this attribute belongs to, by AttributeGroup key.

thresholds: Option<Thresholds>

Optional two-tier thresholds (language-calibrated).

omit_at: f64

Value at which this metric carries no signal and is omitted from the node (absent in the JSON, blank in the viewer). 0 for almost everything; 1 for cyclomatic (McCabe’s floor — a function-less file would otherwise report a vacuous 1). Published so the frontend knows what an absent cell means (and may treat it as this value when sorting). Default 0 is omitted from the wire.

Implementations

impl AttributeSpec

pub fn new(value_type: ValueType, label: &str) -> Self

A minimal spec with just a type + label (the common structural case).

Trait Implementations

impl Clone for AttributeSpec

fn clone(&self) -> AttributeSpec

Returns a duplicate of the value.

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

impl Debug for AttributeSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AttributeSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for AttributeSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
