Enum Error 

pub enum Error {
    InvalidWeight {
        weight: f64,
    },
    InvalidBudget {
        budget: f64,
    },
    TooManyAttacks {
        attacks: usize,
        limit: usize,
    },
    Dung(Error),
}

Errors that can occur in the argumentation-weighted crate.

Variants

InvalidWeight

An attack weight was non-finite (NaN or infinity) or negative. Dunne 2011 requires non-negative finite weights.

Fields

weight: f64

The weight that failed validation.

InvalidBudget

A budget value was non-finite or negative.

Fields

budget: f64

The budget that failed validation.

TooManyAttacks

A weighted framework exceeded the Dunne 2011 subset-enumeration attack-count limit. The exact semantics enumerate the power set of attacks, so the limit caps memory+time at 2^limit subsets.

Fields

attacks: usize

The number of attacks in the offending framework.

limit: usize

The current enumeration limit.

Dung(Error)

An error from the underlying Dung layer (e.g., framework too large for subset enumeration).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
