Enum GraphError 

pub enum GraphError {
    CycleDetected,
    BadlyFormedGraph,
    NoRootNode,
    MultipleRootNodes,
    NodeNotFound,
    InvalidTrimNodes,
    ReducerError(ReducerError),
}

Error types for methods of graph module.

Variants

CycleDetected

Cycle detected in graph.

BadlyFormedGraph

Cycle detected or graph missing dependencies.

NoRootNode

No root node found in graph.

MultipleRootNodes

There can’t be more than one root node in a graph.

NodeNotFound

Requested node not found in graph.

InvalidTrimNodes

Requested trim nodes not found in graph.

ReducerError(ReducerError)

Requested trim nodes not found in graph.

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> GraphError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Error for GraphError

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 From<GraphError> for DocumentBuilderError

fn from(source: GraphError) -> Self

Converts to this type from the input type.

impl From<GraphError> for DocumentError

fn from(source: GraphError) -> Self

Converts to this type from the input type.

impl From<ReducerError> for GraphError

fn from(source: ReducerError) -> Self

Converts to this type from the input type.
