Enum QueryPredicateError 

pub enum QueryPredicateError {
    ConnPoolQuery(AcquireThenQueryError),
    MissingLenBytes,
    InvalidLenBytes,
    Decode(PredicateDecodeError),
}

Any errors that might occur while querying for predicates.

Variants

ConnPoolQuery(AcquireThenQueryError)

A DB query failure occurred.

MissingLenBytes

The queried predicate is missing the word that encodes its length.

InvalidLenBytes

The queried predicate length was invalid.

Decode(PredicateDecodeError)

Failed to decode the queried predicate.

Trait Implementations

impl Debug for QueryPredicateError

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

Formats the value using the given formatter.

impl Display for QueryPredicateError

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

Formats the value using the given formatter.

impl Error for QueryPredicateError

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.
