Enum Error 

pub enum Error {
    ArgumentNotFound(String),
    Parse(String),
    Aspic(String),
    TooLarge {
        arguments: usize,
        limit: usize,
    },
}

Errors that can occur in the argumentation crate.

Variants

ArgumentNotFound(String)

An argument referenced in an operation was not present in the framework. The payload is a Debug rendering of the missing argument when available.

Parse(String)

A parser failed to decode input.

Aspic(String)

An ASPIC+ operation failed structurally (e.g., cyclic rule dependencies, rule references a literal not in the language).

TooLarge

An extension-enumeration call was rejected because the framework is too large for the subset-enumeration algorithm. Use a SAT-based semantics entry point (future) for frameworks above this threshold.

Fields

arguments: usize

Number of arguments in the framework.

limit: usize

Enumeration limit (currently 22, see crate::ENUMERATION_LIMIT).

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.
