Struct Pattern 

pub struct Pattern {
    pub name: String,
    pub edges: Vec<(u32, u32)>,
    pub min_nodes: usize,
    pub max_nodes: Option<usize>,
    pub severity: Severity,
}

Pattern specification for matching

Fields

name: String

Pattern name

edges: Vec<(u32, u32)>

Pattern edges (source, target) - node IDs are local to the pattern

min_nodes: usize

Minimum number of nodes in the pattern

max_nodes: Option<usize>

Maximum number of nodes (None = unbounded)

severity: Severity

Severity if found

Implementations

impl Pattern

pub fn new(name: String, edges: Vec<(u32, u32)>, severity: Severity) -> Pattern

Create a new pattern

pub fn god_class(min_callees: usize) -> Pattern

Create a “God Class” pattern (node with many outgoing edges)

Detects functions that call too many other functions (high fan-out)

pub fn circular_dependency(cycle_length: usize) -> Pattern

Create a “Circular Dependency” pattern (cycle of length N)

Detects function call cycles

pub fn dead_code() -> Pattern

Create a “Dead Code” pattern (node with no incoming edges)

Detects uncalled functions

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.
