Struct ModelError 

#[non_exhaustive]
pub struct ModelError {
    pub kind: ModelErrorKind,
    pub model: Option<String>,
    pub expected_sha256: Option<String>,
    pub path: Option<PathBuf>,
    pub install_command: Option<String>,
    pub expected_ort: Option<String>,
    pub found_ort: Option<String>,
    /* private fields */
}

A shared-layer failure.

Carries the structured fields callers branch on; converts into std::io::Error via [std::io::Error::other] so pdf-engine surfaces it as EngineError::Io without a new variant, downcastable through model_error.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: ModelErrorKind

What went wrong.

model: Option<String>

The spec name, or "onnxruntime-1.23.2" when the missing or mismatched file is the runtime library itself.

expected_sha256: Option<String>

The digest the file was checked against (ModelErrorKind::ChecksumMismatch).

path: Option<PathBuf>

The path looked at: the model file, or the library.

install_command: Option<String>

The spec’s install command, shown verbatim when the model is missing.

expected_ort: Option<String>

The runtime version required (ModelErrorKind::VersionMismatch).

found_ort: Option<String>

The runtime version the library reported (ModelErrorKind::VersionMismatch).

Implementations

impl ModelError

pub fn feature_not_compiled(spec: &ModelSpec, feature: &'static str) -> Self

The tier is not compiled into this build: a model tier was asked for on a build without the cargo feature that runs it (#641).

ModelErrorKind::ModelNotAvailable, naming the feature to rebuild with; the Display appends the spec’s install command, so the message names both the feature and the install.

Trait Implementations

impl Clone for ModelError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelError

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

Formats the value using the given formatter.

impl Display for ModelError

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

Formats the value using the given formatter.

impl Error for ModelError

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<ModelError> for Error

fn from(e: ModelError) -> Self

Converts to this type from the input type.
