Struct UnknownNode 

pub struct UnknownNode {
    pub index: usize,
    pub node: u32,
    pub node_count: u32,
}

Error returned by reachable when the edge list contains a node index outside 0..node_count.

Fields

index: usize

Index into edges of the offending pair.

node: u32

The out-of-range node id.

node_count: u32

Total node count the graph was constructed with.

Trait Implementations

impl Clone for UnknownNode

fn clone(&self) -> UnknownNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UnknownNode

impl Debug for UnknownNode

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

Formats the value using the given formatter.

impl Display for UnknownNode

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

impl Eq for UnknownNode

impl Error for UnknownNode

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<UnknownNode> for ReachableError

fn from(error: UnknownNode) -> Self

Converts to this type from the input type.

impl PartialEq for UnknownNode

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

Equality operator ==.

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

Inequality operator !=.
