Enum TraversalBuildError 

#[non_exhaustive]
pub enum TraversalBuildError {
    NoNodes,
    RootOutOfRange,
}

Invalid traversal-engine 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.

NoNodes

At least one node is required.

RootOutOfRange

The root is outside the node universe.

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
