}

Errors produced by fetch_model.

Variants

InsecureUrl(String)

source_url was not https://.

Transport(String)

HTTP transport error (DNS, TLS, refused connection).

HttpStatus(u16)

Server returned a non-success status.

Io(Error)

I/O error reading body or writing dest.

HashMismatch

SHA-256 mismatch between downloaded bytes and sha256_hex. File has been moved into locks/quarantine/.

Fields

expected: String

What the config said.

actual: String

What we computed.

quarantine_path: PathBuf

Where the bad bytes were moved.

Finalise(Error)

Atomic rename of the partial into the final blob path failed.

LockContended

Another producer holds the per-name lock. Another daemon is currently fetching this same model.

Fields

name: String

Model name that was contended.

NoSourceNoManifest

CLI-only mode: source_url is empty AND no manifest exists. Operator must either set source_url or pre-write a manifest + blob.

Fields

name: String

Model name that couldn’t be resolved.

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<Error> for FetchError

fn from(source: Error) -> Self

Converts to this type from the input type.
