Enum Error

pub enum Error {
    SizeOverflow,
    SizeMismatch,
    CapacityOverflow,
    LengthInconsistent,
    IndexOutOfBounds,
    SquareMatrixRequired,
    ShapeNotConformable,
}

An enum for error types.

Variants

SizeOverflow

Error when the size exceeds usize::MAX.

SizeMismatch

Error when the size of the shape does not match the size of the underlying data.

CapacityOverflow

Error when attempting to allocate more than isize::MAX bytes of memory.

Refer to vec and The Rustonomicon for more information.

LengthInconsistent

Error when converting to a matrix from rows or columns with inconsistent lengths.

IndexOutOfBounds

Error for accessing an index out of bounds.

SquareMatrixRequired

Error when a square matrix is required but the current one does not satisfy this requirement.

ShapeNotConformable

Error when the shapes of two matrices are not conformable for the intended operation.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
