Implementations

impl MathError

pub fn convergence_failed(iterations: u32, residual: f64) -> Self

Creates a convergence failed error.

pub fn invalid_input(reason: impl Into<String>) -> Self

Creates an invalid input error.

pub fn insufficient_data(required: usize, actual: usize) -> Self

Creates an insufficient data error.

Trait Implementations

impl Clone for MathError

fn clone(&self) -> MathError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MathError

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

Formats the value using the given formatter.

impl Display for MathError

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

Formats the value using the given formatter.

impl Error for MathError

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.
