Errors that can occur during model fetching.

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.

Api(ApiError)

The hf-hub API returned an error.

Io

An I/O error occurred while accessing the local filesystem.

Fields

path: PathBuf

The path that caused the error.

source: Error

The underlying I/O error.

RepoNotFound

The repository was not found or is inaccessible.

Fields

repo_id: String

The repository identifier that was not found.

Auth

Authentication failed (missing or invalid token).

Fields

reason: String

Description of the authentication failure.

InvalidPattern

An invalid glob pattern was provided for filtering.

Fields

pattern: String

The glob pattern that failed to parse.

reason: String

Description of the parse error.

Checksum

SHA256 checksum mismatch after download.

Fields

filename: String

The filename that failed verification.

expected: String

The expected SHA256 hex digest.

actual: String

The actual SHA256 hex digest computed from the file.

Timeout

A download operation timed out.

Fields

filename: String

The filename that timed out.

seconds: u64

The timeout duration in seconds.

PartialDownload

One or more files failed to download.

Contains the successful path and a list of per-file failures.

Fields

path: Option<PathBuf>

The snapshot directory (if any files succeeded).

failures: Vec<FileFailure>

Per-file failure details.

ChunkedDownload

A chunked (multi-connection) download failed.

Fields

filename: String

The filename that failed.

reason: String

Description of the failure.

Http(String)

An HTTP request to the HuggingFace API failed.

InvalidArgument(String)

An invalid argument was provided.

Trait Implementations

impl Debug for FetchError

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

Formats the value using the given formatter.

impl Display for FetchError

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

Formats the value using the given formatter.

impl Error for FetchError

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<ApiError> for FetchError

fn from(source: ApiError) -> Self

Converts to this type from the input type.
