}

An error associated with a projection.

Variants

Empty

Empty projection.

InvalidProjection

Projection attempts to project from a smaller to a larger shape.

Fields

dimension: usize

Dimension in which projection fails.

from: usize

Shape from which to project from.

to: usize

Shape from which to project to.

UnequalDimensions

Projection attempts to project from one dimension to another.

Fields

from: usize

Trait Implementations

impl Debug for ProjectionError

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

Formats the value using the given formatter.

impl Display for ProjectionError

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

Formats the value using the given formatter.

impl Error for ProjectionError

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<ProjectionError> for Error

fn from(e: ProjectionError) -> Self

Converts to this type from the input type.
