Errors raised by the meta-plugin.

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.

BodyParse(String)

Declared body could not be parsed.

NativeShadow(String)

Declared qname conflicts with an existing native registration.

DependencyMissing

Declared plugin depends on a missing or already-dropped qname.

Fields

dependent: String

The dependent’s qname.

dep: String

The missing dependency’s qname.

DependencyCycle(Vec<String>)

Cyclic dependencies among declared plugins.

Persistence(PersistenceError)

A persistence backend reported a failure.

Registration(String)

Registration into the PluginRegistry failed.

CapabilityDenied(String)

The principal lacks a capability required by the declaration.

Trait Implementations

impl Debug for CustomError

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

Formats the value using the given formatter.

impl Display for CustomError

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

Formats the value using the given formatter.

impl Error for CustomError

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<PersistenceError> for CustomError

fn from(source: PersistenceError) -> Self

Converts to this type from the input type.
