pub enum NodeMapError<T, B> {
    Conflicting(ConflictingIndexes<T, B>),
    GeneratedId(GeneratedIdError),
}

Error returned by node-map construction.

Variants

Conflicting(ConflictingIndexes<T, B>)

A node was given two different @index values.

GeneratedId(GeneratedIdError)

A blank node identifier could not be generated.

Trait Implementations

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
