Top-level error type for sqry-nl operations.

Variants

Preprocess(PreprocessError)

Preprocessing failed (Unicode normalization, input validation)

Extractor(ExtractorError)

Entity extraction failed

Classifier(ClassifierError)

Intent classification failed

Assembler(AssemblerError)

Command assembly failed

Validator(ValidatorError)

Validation failed (safety checks)

Cache(CacheError)

Cache operation failed

Config(String)

Configuration error

Io(Error)

I/O error

ModelDirNotFound(String)

Resolved model directory does not exist on disk.

ChecksumMismatch

Checksum of an on-disk model file does not match the manifest.

Fields

file: String

expected: String

actual: String

ChecksumsMissing

checksums.json (or equivalent integrity manifest) is absent from the model directory.

ChecksummedFileMissing(String)

A file referenced by the integrity manifest is missing from the model directory.

OnnxRuntimeMissing

ONNX Runtime shared library could not be loaded at runtime.

Fields

hint: String

Operator-facing remediation hint (populated in NL08).

ManifestSha256Mismatch

Top-level manifest SHA-256 does not match the expected pinned value.

Raised by NL03’s downloader when the streaming SHA-256 computed over the freshly downloaded archive bytes does not match the manifest.json.sha256 value baked into the binary. Always fatal — there is no --allow-unverified-model opt-out for tampering on a trusted-mode payload.

Fields

file: String

The archive file name from the manifest (e.g. sqry-models-v1.0.0.tar.gz).

expected: String

SHA-256 hex from the trusted baked-in manifest.

actual: String

SHA-256 hex computed over the on-the-wire bytes.

ManifestParseFailed(Error)

Model manifest could not be parsed as JSON.

DownloadDisabled

Network download was attempted but allow_model_download is false.

DownloadFailed(String)

Network download failed (transport, HTTP status, or post-fetch I/O).

Trait Implementations

impl Debug for NlError

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

Formats the value using the given formatter.

impl Display for NlError

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

Formats the value using the given formatter.

impl Error for NlError

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
