Enum QueryError

pub enum QueryError {
    Overflow,
    InvalidString,
    MiscellaneousDecodingError,
    InvalidIndexes,
    MiscellaneousEvaluationError,

}

Verifiable query errors

Variants

Overflow

The query result overflowed. This does not mean that the verification failed. This just means that the database was supposed to respond with a result that was too large.

InvalidString

The query result string could not be decoded. This does not mean that the verification failed. This just means that the database was supposed to respond with a string that was not valid UTF-8.

MiscellaneousDecodingError

Decoding errors other than overflow and invalid string.

InvalidIndexes

Indexes are invalid.

MiscellaneousEvaluationError

Miscellaneous evaluation error.

ProofError

The proof failed to verify.

Fields

source: ProofError

The underlying source error

InvalidTable

The table data was invalid. This should never happen because this should get caught by the verifier before reaching this point.

Fields

source: OwnedTableError

The underlying source error

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

where Self: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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.

impl ErrorCompat for QueryError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
