#[non_exhaustive]
pub enum NavigationError {
    RouteNotFound {
        path: String,

Detailed error variants that can occur during navigation.

Implements std::error::Error and Display for idiomatic error handling.

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.

RouteNotFound

Route not found.

Fields

path: String

The path that could not be resolved.

GuardBlocked

Fields

reason: String

Reason the guard denied access.

InvalidParams

Invalid route parameters.

Fields

message: String

NavigationFailed

Navigation failed.

Fields

message: String

Description of the failure.

Custom

Trait Implementations

impl Clone for NavigationError

fn clone(&self) -> NavigationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NavigationError

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

Formats the value using the given formatter.

impl Display for NavigationError

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

Formats the value using the given formatter.

impl Error for NavigationError

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.
