    SerializationError(SerializationError),
    ParquetError(ParquetError),
    ModelError(String),
    InvalidModelFile(String),

Re-exported model I/O utilities.

Provides model persistence, export/import, and file management capabilities for trained gradient boosting models. Errors that can occur during model I/O operations.

This error type covers all failure modes: file system errors, serialization failures, version mismatches, integrity violations, and missing models.

Variants

IoError(Error)

File system I/O error.

SerializationError(SerializationError)

Model serialization/deserialization error.

ParquetError(ParquetError)

Parquet file reading error.

ModelError(String)

General model error (e.g., untrained model).

InvalidModelFile(String)

Model file is invalid or corrupted.

VersionMismatch

Version incompatibility between saved model and current library.

Fields

expected: String

actual: String

UnsupportedFormat

Unsupported file format.

Fields

format: String

ModelNotFound(String)

Model file not found at specified path.

Trait Implementations

impl Debug for ModelIOError

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

Formats the value using the given formatter.

impl Display for ModelIOError

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

Formats the value using the given formatter.

impl Error for ModelIOError

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.
