Enum EvidenceError 

pub enum EvidenceError {
    EmptyFocalSet,
    NotNormalised {
        total: f64,
    },
    BadMass {
        value: f64,
    },
    ConflictExceeded {
        conflict: f64,
        threshold: f64,
    },
    TotalConflict,
}

Why a combination was refused.

Variants

EmptyFocalSet

a focal set was empty, which §4.1 forbids

NotNormalised

masses did not sum to 1 (within tolerance)

Fields

total: f64

BadMass

negative or non-finite mass

Fields

value: f64

ConflictExceeded

the sources contradict each other beyond the caller’s threshold — the guard of §4.2

Fields

conflict: f64

threshold: f64

TotalConflict

total conflict: every pair of focal sets is disjoint, so Dempster’s rule divides by zero

Trait Implementations

impl Clone for EvidenceError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvidenceError

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

Formats the value using the given formatter.

impl Display for EvidenceError

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

Formats the value using the given formatter.

impl Error for EvidenceError

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 EvidenceError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
