Enum GraphError

pub enum GraphError {
    NodeIxLimit,
    EdgeIxLimit,
    NodeMissed(usize),
    NodeOutBounds,
}

The error type for fallible Graph & StableGraph operations.

Variants

NodeIxLimit

The Graph is at the maximum number of nodes for its index.

EdgeIxLimit

The Graph is at the maximum number of edges for its index.

NodeMissed(usize)

The node with the specified index is missing from the graph.

NodeOutBounds

Node indices out of bounds.

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> GraphError

Returns a copy of the value.

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

Performs copy-assignment from source.

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 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

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.
