Enum ClingoError 

pub enum ClingoError {
    NulError(NulError),
    Utf8Error(Utf8Error),
    FFIError {
        msg: &'static str,
    },
    InternalError {
        msg: &'static str,
        code: ErrorCode,
        last: &'static str,
    },
    ExternalError(ExternalError),
}

ClingoError in the rust wrapper, like null pointers or failed matches of C enums.

Includes internal error from the clingo library.

Note: Errors can only be recovered from if explicitly mentioned; most functions do not provide strong exception guarantees. This means that in case of errors associated objects cannot be used further.

Trait Implementations

impl Debug for ClingoError

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

Formats the value using the given formatter.

impl Display for ClingoError

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

Formats the value using the given formatter.

impl Error for ClingoError

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.
