Enum GraphError 

pub enum GraphError {
    DuplicateFinding(FindingId),
    UnknownFinding(FindingId),
    DuplicateEdge {
        cause: FindingId,
        effect: FindingId,
    },
    Cycle {
        cycle: Vec<FindingId>,
    },
}

Rejected FindingGraph mutations. Every invalid state is an error, not a panic — callers decide how to surface it.

Variants

DuplicateFinding(FindingId)

add_finding saw an id that is already in the graph.

UnknownFinding(FindingId)

add_edge referenced an id with no finding in the graph.

DuplicateEdge

add_edge saw a cause → effect pair that is already stored.

Fields

cause: FindingId

effect: FindingId

Cycle

add_edge would close a loop; the path lists the finding ids that would form it (first and last entry are the same id).

Fields

cycle: Vec<FindingId>

Trait Implementations

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for GraphError

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 PartialEq for GraphError

fn eq(&self, other: &GraphError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
