Struct NodeError 

pub struct NodeError {
    pub node_error: Box<dyn Error + Send + Sync>,
    pub transition: Option<Arc<Transition>>,
    pub node_id: usize,
}

Wraps an error produced by a specific node execution.

Fields

node_error: Box<dyn Error + Send + Sync>

The original node error.

transition: Option<Arc<Transition>>

The transition that would have been applied after this node, when available.

node_id: usize

The numeric identifier of the failing node.

Implementations

impl NodeError

pub fn new( node_error: impl Into<Box<dyn Error + Send + Sync>>, node_id: usize, transition: Option<Transition>, ) -> Self

Creates a new node error tied to node_id.

Trait Implementations

impl Debug for NodeError

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

Formats the value using the given formatter.

impl Display for NodeError

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

Formats the value using the given formatter.

impl Error for NodeError

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<NodeError> for TaskError

fn from(source: NodeError) -> Self

Converts to this type from the input type.
