Enum NormalError 

pub enum NormalError {
    SdNotPositive(f64),
    MeanNotFinite(f64),
    SdNotFinite(f64),
    XNotFinite(f64),
    PNotInRange(f64),
    QNotInRange(f64),
    PQSumNotOne {
        p: f64,
        q: f64,
    },
}

Errors that can arise constructing a Normal or evaluating its inverse routines.

Variants

SdNotPositive(f64)

The standard deviation σ was not strictly positive.

MeanNotFinite(f64)

The mean μ was not finite.

SdNotFinite(f64)

The standard deviation σ was not finite.

XNotFinite(f64)

The argument x was not finite.

PNotInRange(f64)

The probability p fell outside [0 . . 1] (or was non-finite).

QNotInRange(f64)

The probability q fell outside [0 . . 1] (or was non-finite).

PQSumNotOne

The pair (p, q) is not complementary (|p + q − 1| > 3 ε). Mirrors CDFLIB’s cdfnor status 3 (cdflib.f90:5659).

Fields

p: f64

q: f64

Trait Implementations

impl Clone for NormalError

fn clone(&self) -> NormalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NormalError

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

Formats the value using the given formatter.

impl Display for NormalError

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

Formats the value using the given formatter.

impl Error for NormalError

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 NormalError

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

impl Copy for NormalError

impl StructuralPartialEq for NormalError
