Enum GraphError 

#[non_exhaustive]
pub enum GraphError {
    Cyclic,
    IncompatiblePorts,
    InvalidCapacity,
    InvalidEdgeIndex,
    OccupancySampleFailed(EdgeIndex),
}

Graph validation and wiring errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cyclic

The graph contains a cycle.

IncompatiblePorts

Port schema or memory placement is incompatible across an edge.

InvalidCapacity

Queue capacity or watermark configuration is invalid.

InvalidEdgeIndex

Invalid graph index used.

OccupancySampleFailed(EdgeIndex)

Failed to sample occupancy for the given edge (e.g., poisoned lock or device error).

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> GraphError

Returns a duplicate 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

Available on crate feature std only.

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<GraphError> for RuntimeError

fn from(e: GraphError) -> Self

Converts to this type from the input type.

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.
