Enum FuzzyError 

pub enum FuzzyError {
    VariableNotFound(String),
    SetNotFound {
        variable: String,
        set: String,
    },
    DuplicateVariable(String),
    NoRulesForOutput(String),
    NumericalError(String),
}

Errors produced by FuzzyLogicEngine and related types.

Variants

VariableNotFound(String)

A referenced variable does not exist in the engine.

SetNotFound

A referenced set does not exist inside a variable.

Fields

variable: String

set: String

DuplicateVariable(String)

Attempt to add a variable that is already registered.

NoRulesForOutput(String)

infer was called but no rule targets the requested output variable.

NumericalError(String)

A numerical issue prevented completing the computation (e.g. division by zero in defuzzification when all membership degrees are zero).

Trait Implementations

impl Clone for FuzzyError

fn clone(&self) -> FuzzyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FuzzyError

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

Formats the value using the given formatter.

impl Display for FuzzyError

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

Formats the value using the given formatter.

impl Error for FuzzyError

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.
