Enum RealError 

pub enum RealError {
    NonFiniteValue {
        name: &'static str,
        value: f64,
    },
    NonFiniteTolerance(f64),
    NegativeTolerance(f64),
    InvalidInterval {
        min: f64,
        max: f64,
    },
}

Errors returned by validated real-number helpers.

Variants

NonFiniteValue

A real-number component must be finite.

Fields

name: &'static str

The input name that rejected the value.

value: f64

The invalid value.

NonFiniteTolerance(f64)

A comparison tolerance must be finite.

NegativeTolerance(f64)

A comparison tolerance must not be negative.

InvalidInterval

An interval must have min <= max.

Fields

min: f64

The lower bound candidate.

max: f64

The upper bound candidate.

Trait Implementations

impl Clone for RealError

fn clone(&self) -> RealError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RealError

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

Formats the value using the given formatter.

impl Display for RealError

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

Formats the value using the given formatter.

impl Error for RealError

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 RealError

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