Enum TestMatrixError 

pub enum TestMatrixError {
    InvalidDimension {
        param: String,
        value: usize,
    },
    InvalidDensity {
        density: String,
    },
    ConstructionError {
        description: String,
    },
}

Error type for test matrix generation.

Variants

InvalidDimension

Invalid dimensions (zero or too large).

Fields

param: String

Description of the invalid parameter.

value: usize

The invalid value.

InvalidDensity

Density out of valid range [0, 1].

Fields

density: String

The invalid density value.

ConstructionError

Matrix construction failed internally.

Fields

description: String

Description of the failure.

Trait Implementations

impl Clone for TestMatrixError

fn clone(&self) -> TestMatrixError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TestMatrixError

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

Formats the value using the given formatter.

impl Display for TestMatrixError

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

Formats the value using the given formatter.

impl Error for TestMatrixError

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 PartialEq for TestMatrixError

fn eq(&self, other: &TestMatrixError) -> 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.
