Enum PredicateError

pub enum PredicateError<E> {
    InvalidNodeEdges(usize),
    ProgramErrors(ProgramErrors<E>),
    ConstraintsUnsatisfied(ConstraintsUnsatisfied),
    Mutations(MutationsError),
}

check_predicate error.

Variants

InvalidNodeEdges(usize)

Failed to retrieve edges for a node, indicating that the predicate’s graph is invalid.

ProgramErrors(ProgramErrors<E>)

The execution of one or more programs failed.

ConstraintsUnsatisfied(ConstraintsUnsatisfied)

One or more of the constraints were unsatisfied.

Mutations(MutationsError)

One or more of the mutations were invalid.

Trait Implementations

impl<E: Debug> Debug for PredicateError<E>

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

Formats the value using the given formatter.

impl<E> Display for PredicateError<E>

where ProgramErrors<E>: Display,

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

Formats the value using the given formatter.

impl<E> Error for PredicateError<E>

where ProgramErrors<E>: Error + 'static, Self: Debug + Display,

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.
