Enum ModelRegistryError 

pub enum ModelRegistryError {
    UnknownModel(String),
    UnknownVersion {
        model: String,
        version: u32,
    },
    VersionArchived {
        model: String,
        version: u32,
    },
    LockPoisoned,
    Backend(String),
}

Error surface for registry operations.

Variants

UnknownModel(String)

The model name is not registered.

UnknownVersion

The (model, version) pair is not registered.

Fields

model: String

version: u32

VersionArchived

USE VERSION pointed at an archived version.

Fields

model: String

version: u32

LockPoisoned

Internal mutex poisoned — should not happen in practice, but the surface needs a variant because we never panic on poison.

Backend(String)

Wrapped error from the persistence backend.

Trait Implementations

impl Clone for ModelRegistryError

fn clone(&self) -> ModelRegistryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelRegistryError

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

Formats the value using the given formatter.

impl Display for ModelRegistryError

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

Formats the value using the given formatter.

impl Error for ModelRegistryError

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<T> From<PoisonError<T>> for ModelRegistryError

fn from(_: PoisonError<T>) -> ModelRegistryError

Converts to this type from the input type.

impl PartialEq for ModelRegistryError

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