Enum StepGraphBuildError 

#[non_exhaustive]
pub enum StepGraphBuildError {
    EdgeEndpointOutOfRange,
    DuplicateEdge,
}

Invalid step-graph configuration.

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.

EdgeEndpointOutOfRange

At least one edge endpoint is outside the node universe.

DuplicateEdge

Duplicate edges are not admitted.
