Enum ProbabilityError 

pub enum ProbabilityError {
    NonFiniteProbability(f64),
    ProbabilityOutOfRange(f64),
    ZeroTotal,
    PartExceedsTotal {
        part: u64,
        total: u64,
    },
}

Errors returned by validated probability helpers.

Variants

NonFiniteProbability(f64)

A probability value must be finite.

ProbabilityOutOfRange(f64)

A probability value must stay in the closed interval [0, 1].

ZeroTotal

A ratio denominator must be greater than zero.

PartExceedsTotal

A ratio numerator must not exceed the denominator.

Fields

part: u64

The numerator.

total: u64

The denominator.

Trait Implementations

impl Clone for ProbabilityError

fn clone(&self) -> ProbabilityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProbabilityError

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

Formats the value using the given formatter.

impl Display for ProbabilityError

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

Formats the value using the given formatter.

impl Error for ProbabilityError

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 ProbabilityError

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