Enum ShapeMismatch 

#[non_exhaustive]
pub enum ShapeMismatch {
    IncompatibleShapes {
        lhs: SmallVec<[usize; 8]>,
        rhs: SmallVec<[usize; 8]>,

}

Structured facts describing why two tensor shapes are incompatible.

Examples

use tenferro_tensor_core::{ShapeMismatch, ShapeVec};

let mismatch = ShapeMismatch::IncompatibleShapes {
    lhs: ShapeVec::from_vec(vec![2, 3]),
    rhs: ShapeVec::from_vec(vec![2, 4]),
};
assert!(mismatch.to_string().contains("incompatible shapes"));

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.

Trait Implementations

impl Clone for ShapeMismatch

fn clone(&self) -> ShapeMismatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeMismatch

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

Formats the value using the given formatter.

impl Display for ShapeMismatch

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

Formats the value using the given formatter.

impl Error for ShapeMismatch

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<ShapeMismatch> for ValidationError

fn from(error: ShapeMismatch) -> ValidationError

Converts to this type from the input type.

impl PartialEq for ShapeMismatch

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

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

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

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