Enum StratificationError 

pub enum StratificationError {
    NegativeCycle {
        participating_nodes: Vec<String>,
    },
    UnstratifiableGraph(String),
}

Errors produced by the stratification algorithm.

Variants

NegativeCycle

The graph contains a cycle involving at least one negative edge.

Fields

participating_nodes: Vec<String>

Names of the nodes that participate in the negative cycle.

UnstratifiableGraph(String)

General stratification failure with a descriptive message.

Trait Implementations

impl Clone for StratificationError

fn clone(&self) -> StratificationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StratificationError

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

Formats the value using the given formatter.

impl Display for StratificationError

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

Formats the value using the given formatter.

impl Error for StratificationError

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.
