Errors returned when building a modal graph from transport link metadata.

Variants

MissingLink(u64)

Link metadata referenced a link that does not exist in the link space.

EndpointMismatch

Link metadata endpoints disagree with the topology held by the link space.

Fields

link_id: u64

Link identifier.

metadata_from: u64

Source node from metadata.

metadata_to: u64

Destination node from metadata.

space_from: u64

Source node from link space.

space_to: u64

Destination node from link space.

InvalidCost

A link’s current travel time could not be used as a routing cost.

Fields

link_id: u64

Link identifier.

cost: f64

Computed cost.

Trait Implementations

impl Clone for ModalGraphBuildError

fn clone(&self) -> ModalGraphBuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModalGraphBuildError

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

Formats the value using the given formatter.

impl Display for ModalGraphBuildError

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

Formats the value using the given formatter.

impl Error for ModalGraphBuildError

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 PartialEq for ModalGraphBuildError

fn eq(&self, other: &ModalGraphBuildError) -> 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.
