Errors that can occur during matrix cross interpolation operations

Examples

use tensor4all_tcicore::MatrixCIError;

let err = MatrixCIError::DimensionMismatch {
    expected_rows: 3,
    expected_cols: 3,
    actual_rows: 2,
    actual_cols: 2,
};
assert!(format!("{err}").contains("Dimension mismatch"));

let err = MatrixCIError::FullRank;
assert!(format!("{err}").contains("full rank"));

// Matching on error variants
match err {
    MatrixCIError::FullRank => assert!(true),
    _ => panic!("unexpected variant"),
}

Trait Implementations

impl Debug for MatrixCIError

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

Formats the value using the given formatter.

impl Display for MatrixCIError

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

Formats the value using the given formatter.

impl Error for MatrixCIError

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.
