Enum RegistryError 

pub enum RegistryError {
    RegistryLock,
    TypeMismatch {
        type_name: &'static str,
    },
    TypeNotFound {
        type_name: &'static str,
    },
}

Error type for registry operations.

All fallible registry operations return this error type to indicate what went wrong during the operation.

Variants

RegistryLock

Failed to acquire the registry lock (lock poisoning).

This is automatically recovered in most operations, but exposed here for completeness.

TypeMismatch

Type mismatch during downcast (should never happen in practice).

Includes the type name that was requested.

Fields

type_name: &'static str

The type name that was requested

TypeNotFound

The requested type was not found in the registry.

Includes the type name that was requested.

Fields

type_name: &'static str

The type name that was requested

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, f: &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 PartialEq for RegistryError

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