Errors that can occur during path resolution

Variants

EmptyPath

The path string was empty or contained only separators

AliasNotFound

No child of the current node matched the given alias segment

Fields

segment: String

parent_alias: Option<String>

UnderscoreOnNonCollector

_ was used on a node that is not a collector (no inner/outer split)

Fields

node_alias: String

StarOnSingleCardinality

* was used on a single-cardinality node

Fields

node_alias: String

NoNodegroup

The target node has no nodegroup_id

Fields

node_alias: String

ModelNotInitialized(String)

Model data (nodes, edges, etc.) was not available

TilesNotInitialized

Tiles storage was not initialized on the wrapper

Trait Implementations

impl Clone for PathError

fn clone(&self) -> PathError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PathError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PathError

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<String> for PathError

fn from(s: String) -> Self

Converts to this type from the input type.
