Enum Error 

pub enum Error {
    SchemeNotFound(String),
    MissingBinding {
        scheme: String,
        slot: String,
    },
    Scheme(Error),

    Weighted(Error),
    WeightedBipolar(Error),
    MissingProposerBinding {

    },
}

Errors that can occur during argumentation bridge operations.

Variants

SchemeNotFound(String)

A requested scheme key was not found in the registry.

MissingBinding

A required slot binding was missing when instantiating a scheme.

Fields

scheme: String

The name of the scheme that required the binding.

slot: String

The slot that was not bound.

Scheme(Error)

An error propagated from the argumentation-schemes layer.

Dung(Error)

An error propagated directly from the core Dung/ASPIC+ layer.

Bipolar(Error)

An error propagated from the argumentation-bipolar layer.

Weighted(Error)

An error propagated from the argumentation-weighted layer.

WeightedBipolar(Error)

An error propagated from the argumentation-weighted-bipolar layer.

MissingProposerBinding

An affordance passed to StateAcceptanceEval has no "self" binding, so the bridge cannot identify the proposer. The eval defaulted to accept for this action. Surfaces via crate::state::EncounterArgumentationState::drain_errors. Consumers who use a non-"self" proposer slot name should wrap StateAcceptanceEval with a custom implementation.

Fields

affordance_name: String

The affordance name with no "self" binding.

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.
