Struct CycleError 

pub struct CycleError {
    pub cycle: Vec<String>,
}

Error returned when a cycle is detected in the depends graph.

Fields

cycle: Vec<String>

The node IDs forming the cycle, in order. The first and last elements are the same node (closing the loop). Example: ["a", "b", "c", "a"]

Implementations

impl CycleError

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

Creates a new CycleError from a cycle path.

path should be the ordered sequence of nodes in the cycle. The closing node (same as first) will be appended automatically if not already present.

pub fn display_path(&self) -> String

Returns the cycle path as a human-readable string: "a -> b -> c -> a".

Trait Implementations

impl Clone for CycleError

fn clone(&self) -> CycleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CycleError

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

Formats the value using the given formatter.

impl Display for CycleError

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

Formats the value using the given formatter.

impl Error for CycleError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for CycleError

fn eq(&self, other: &CycleError) -> 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.
