Enum CreationError 

#[non_exhaustive]
pub enum CreationError {
    Shape(ShapeError),
    InvalidStep {
        step: f32,
    },
    NonFiniteBound {
        start: f32,
        end: f32,
    },
}

arange／linspace 専用のエラー型。shape（要素数）起因の 不整合は Tensor::zeros 等と同じ ShapeError へ委譲し （From<ShapeError> 実装）、引数自体の不正（step == 0・非有限値） は ShapeError の対象外であるため本型で新設する （rng::RngError と同型の設計。イシュー #1726）。

#[non_exhaustive]: RngError／ShapeError と同じ理由（公開 API 非破壊。.claude/rules/security.md）で後続の検査項目追加に備える。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Shape(ShapeError)

shape 起因の不整合（要素数積のオーバーフロー等）。

InvalidStep

arange の step がゼロまたは非有限（NaN／±inf）。

Fields

step: f32

NonFiniteBound

arange／linspace の start／end が非有限（NaN／±inf）。

Fields

start: f32

end: f32

Trait Implementations

impl Clone for CreationError

fn clone(&self) -> CreationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreationError

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

Formats the value using the given formatter.

impl Display for CreationError

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

Formats the value using the given formatter.

impl Error for CreationError

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<ShapeError> for CreationError

fn from(err: ShapeError) -> CreationError

Converts to this type from the input type.

impl PartialEq for CreationError

fn eq(&self, other: &CreationError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
