Enum ModelError

pub enum ModelError {
    InvalidState { /* private fields */ },
    SerializationError { /* private fields */ },
    PredictionError { /* private fields */ },
    IllegalArgument { /* private fields */ },
    UnknownError { /* private fields */ },
}

Errors raised by a model’s API call.

Variants

InvalidState

The model’s internal state is invalid.

This can occur if the model’s parameters or input data were not initialized correctly.

SerializationError

The model cannot be saved to/loaded from disk.

This can occur if the serialized data was not found, or if the model is in an indeterminate state after deserialization.

PredictionError

The model couldn’t be applied to the test/prediction data.

IllegalArgument

One or more of the arguments passed to the API call are invalid.

UnknownError

The model encountered an unexpected internal error.

Trait Implementations

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 Fail for ModelError

fn name(&self) -> Option<&str>

Returns the “name” of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D>

where D: Display + Send + Sync + 'static, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>

where Self: Sized,

Wraps this failure in a compatibility wrapper that implements std::error::Error.
