Enum CausalError 

pub enum CausalError {
    NodeAlreadyExists(String),
    NodeNotFound(String),
    CycleDetected,
    InvalidEdge(String),
}

Errors that can be produced by the CausalInferenceEngine.

Variants

NodeAlreadyExists(String)

A node with the same identifier already exists in the graph.

NodeNotFound(String)

A referenced node does not exist in the graph.

CycleDetected

Adding the requested edge would create a directed cycle.

InvalidEdge(String)

The edge specification is otherwise invalid.

Trait Implementations

impl Clone for CausalError

fn clone(&self) -> CausalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CausalError

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

Formats the value using the given formatter.

impl Display for CausalError

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

Formats the value using the given formatter.

impl Eq for CausalError

impl Error for CausalError

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 CausalError

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