CyclePath

Struct CyclePath 

Source
pub struct CyclePath {
    pub nodes: Vec<String>,
}
Expand description

A path representing a circular dependency in the schema.

Contains the sequence of type names that form the cycle.

Fields§

§nodes: Vec<String>

Type names in the cycle, in dependency order. For a cycle A → B → C → A, this would be ["A", "B", "C"].

Implementations§

Source§

impl CyclePath

Source

pub fn new(nodes: Vec<String>) -> Self

Create a new cycle path from a list of nodes.

Source

pub fn path_string(&self) -> String

Format the cycle as a readable path string.

§Example
use fraiseql_core::schema::CyclePath;

let cycle = CyclePath::new(vec!["A".to_string(), "B".to_string(), "C".to_string()]);
assert_eq!(cycle.path_string(), "A → B → C → A");
Source

pub fn is_self_reference(&self) -> bool

Check if this is a self-referencing cycle (single node).

Source

pub fn len(&self) -> usize

Get the length of the cycle (number of types involved).

Source

pub fn is_empty(&self) -> bool

Check if the cycle is empty (should never happen in practice).
