Enum GraphFlowContextError 

#[non_exhaustive]
pub enum GraphFlowContextError {
    MissingCurrentNode,
    MissingCurrentPosition,
    ParseNodeIndex(ParseIntError),
    ParseTaskId(BoxDynError),
    DuplicateEntry(MetadataError),
}

An error representing an invalid GraphFlowContext

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingCurrentNode

Missing current node key

MissingCurrentPosition

Missing current position key

ParseNodeIndex(ParseIntError)

Could not parse a node index

ParseTaskId(BoxDynError)

Could not parse a task_id

DuplicateEntry(MetadataError)

Duplicate entry

Trait Implementations

impl Debug for GraphFlowContextError

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

Formats the value using the given formatter.

impl Display for GraphFlowContextError

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

Formats the value using the given formatter.

impl Error for GraphFlowContextError

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.
