Struct CycleWarning 

pub struct CycleWarning {
    pub cycle_path: Vec<String>,
    pub edge_from: String,
    pub edge_to: String,
}

A warning emitted when a new blocking edge would close a cycle.

Contains the cycle path (ordered list of item IDs forming the loop) and the edge that triggered detection.

Fields

cycle_path: Vec<String>

The ordered list of item IDs forming the cycle.

The path starts at the source of the new edge, follows blocking dependencies, and ends at the source again. For example, if adding edge A→B creates cycle A→B→C→A, the path is ["A", "B", "C", "A"].

edge_from: String

The source of the newly added edge (the item being blocked).

edge_to: String

The target of the newly added edge (the blocker).

Implementations

impl CycleWarning

pub fn cycle_len(&self) -> usize

Number of distinct items in the cycle (path length minus the repeated start node).

pub fn is_self_loop(&self) -> bool

Returns true if this is a self-loop (item blocks itself).

pub fn is_mutual_block(&self) -> bool

Returns true if this is a mutual block (2-node cycle: A↔B).

Trait Implementations

impl Clone for CycleWarning

fn clone(&self) -> CycleWarning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CycleWarning

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

Formats the value using the given formatter.

impl Display for CycleWarning

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

Formats the value using the given formatter.

impl PartialEq for CycleWarning

fn eq(&self, other: &CycleWarning) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
