Enum AdjacencyError 

pub enum AdjacencyError {
    NonCanonicalEdge {
        index: usize,
        left: usize,
        right: usize,
    },
    EndpointOutOfRange {
        index: usize,
        right: usize,
        node_count: usize,
    },
    ZeroWeight {
        index: usize,
    },
}

Structured validation errors for declarative adjacency test input.

Variants

NonCanonicalEdge

The edge endpoints are not in canonical order.

Fields

index: usize

Edge index within the declarative input slice.

left: usize

Left endpoint supplied by the caller.

right: usize

Right endpoint supplied by the caller.

EndpointOutOfRange

The right endpoint falls outside the declared node range.

Fields

index: usize

Edge index within the declarative input slice.

right: usize

Out-of-range right endpoint.

node_count: usize

Declared node count for the report.

ZeroWeight

The edge weight violates the positive-weight production contract.

Fields

index: usize

Edge index within the declarative input slice.

Trait Implementations

impl Clone for AdjacencyError

fn clone(&self) -> AdjacencyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdjacencyError

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

Formats the value using the given formatter.

impl Display for AdjacencyError

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

Formats the value using the given formatter.

impl Error for AdjacencyError

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 AdjacencyError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
