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.

MissingArtifact(PathBuf)

Artifact path does not exist.

UnsupportedContainer(PathBuf)

Path is not a supported artifact container.

UnsupportedModelType(String)

Model type is not recognized.

UnsupportedGgufArchitecture(String)

GGUF architecture is not recognized.

MissingGgufArchitecture

GGUF architecture metadata is absent or has the wrong type.

MissingRequiredGgufCompanion

An architecture-required sibling GGUF artifact could not be found.

Fields

role: GgufCompanionRole

Semantic role of the missing companion.

filename_prefix: String

Filename prefix used to discover the companion.

searched_directories: Vec<PathBuf>

Directories searched in priority order.

InvalidArtifact(String)

Header/catalog content is contradictory.

InvalidArchitecturePlan(String)

Architecture-owned artifact planning rejected the inspected inputs.

DuplicateTensor(String)

A tensor name occurred more than once.

SafetensorsShards(SafetensorsShardError)

Canonical SafeTensors shard discovery or path admission failed.

UnsupportedQuantizationPolicy(String)

Requested quantization transformation is unavailable for the artifact.

UnsupportedResidencyPolicy(String)

Requested residency mode is unavailable for the artifact.

UnsupportedLoadingProtocol(LoadingProtocol)

The general model planner cannot satisfy the resolved loader contract.

Io(Error)

Ordinary filesystem error.

Json(Error)

JSON configuration/header error.

Gguf(Error)

GGUF parsing/catalog error.

Catalog(CatalogError)

Neutral tensor catalog error.

Trait Implementations

impl Debug for ArtifactError

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

Formats the value using the given formatter.

impl Display for ArtifactError

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

Formats the value using the given formatter.

impl Error for ArtifactError

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.
