Enum ClosureError 

pub enum ClosureError {
    Cycle {
        first: Ordinal,
        members: Vec<Ordinal>,
    },
    Csr(CsrError),
}

A failure while computing the closure.

Variants

Cycle

The is-a edges contain a cycle through these ordinals.

Fields

first: Ordinal

The first node found on a cycle.

members: Vec<Ordinal>

Every node not reachable from the roots by a topological sweep.

Csr(CsrError)

The adjacency is inconsistent.

Trait Implementations

impl Clone for ClosureError

fn clone(&self) -> ClosureError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClosureError

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

Formats the value using the given formatter.

impl Display for ClosureError

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

Formats the value using the given formatter.

impl Eq for ClosureError

impl Error for ClosureError

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<CsrError> for ClosureError

fn from(source: CsrError) -> Self

Converts to this type from the input type.

impl PartialEq for ClosureError

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

Equality operator ==.

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

Inequality operator !=.
