Enum PhopError 

pub enum PhopError {
    Io(Error),
    Csv(Error),
    Parse(String),
    ShapeMismatch(String),
    NumericalInstability(String),
    NotConverged(String),
    Eval(String),
    Symbolic(String),
    Backend(String),
}

Errors that can arise during data loading, forest evaluation, or discovery.

Variants

Io(Error)

Underlying I/O failure (e.g. reading a CSV file).

Csv(Error)

CSV parsing failure.

Parse(String)

A value could not be parsed as a floating-point number.

ShapeMismatch(String)

Tensor / array shapes were incompatible.

NumericalInstability(String)

A forward/backward pass produced non-finite values.

NotConverged(String)

The optimizer did not reach the configured tolerance.

Eval(String)

Failure while evaluating an autograd graph.

Symbolic(String)

Failure in the symbolic distillation / canonicalization stage.

Backend(String)

Failure in a compute backend (e.g. the CUDA GPU path).

Trait Implementations

impl Debug for PhopError

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

Formats the value using the given formatter.

impl Display for PhopError

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

Formats the value using the given formatter.

impl Error for PhopError

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 PhopError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for PhopError

fn from(source: Error) -> Self

Converts to this type from the input type.
