Errors raised by ComponentRegistry operations.

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.

AlreadyRegistered

Tried to register a name that is already in use.

Fields

name: String

The conflicting name.

NotFound

Tried to unregister a name that is not present.

Fields

name: String

The missing name.

MissingDependency

A factory listed in depends_on was not registered.

Fields

name: String

The component declaring the dependency.

dep: String

The missing dependency name.

Cycle

The dependency graph contains a cycle. The first cycle found is reported as a list of node names.

Fields

cycle: Vec<String>

The cycle, in the order it was discovered.

Init

Init phase failed for a component.

Fields

name: String

Name of the failing component.

message: String

Human-readable error.

Start

Start phase failed for a component.

Fields

name: String

Name of the failing component.

message: String

Human-readable error.

Stop

Stop phase failed for a component. Other components continue to stop regardless.

Fields

name: String

Name of the failing component.

message: String

Human-readable error.

Reload

A reload (hot-swap) operation failed.

Fields

name: String

Name of the component being reloaded.

message: String

Human-readable error.

LockPoisoned

Internal lock acquisition failed.

TypeMismatch

A typed downcast failed via ComponentRegistry::get.

Fields

name: String

The name that was looked up.

type_id: TypeId

The actual TypeId of the stored instance.

AlreadyInitialized

Tried to init_all after a previous init_all already started or completed. Use explicit unregister to re-init.

Fields

name: String

The already-initialized name.

Trait Implementations

impl Debug for RegistryError

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

Formats the value using the given formatter.

impl Display for RegistryError

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

Formats the value using the given formatter.

impl Error for RegistryError

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<RegistryError> for ManagedError

fn from(source: RegistryError) -> Self

Converts to this type from the input type.
