An error thrown by the engine.

Variants

InvalidCharacterInRegex

Invalid character used in regex.

OperationTimeOutError

The operation took too much time.

AutomatonShouldBeDeterministic

The given automaton should be deterministic.

AutomatonHasTooManyStates

The automaton has too many states.

RegexSyntaxError(String)

The regular expression can not be parsed.

TooMuchTerms(usize, usize)

Too many terms are used in the operation.

ConditionInvalidRange

The provided range can not be built from the spanning set.

ConditionIndexOutOfBound

The provided index is out of bound of the condition.

TokenError(TokenError)

There is an error with one of the token.

Implementations

impl EngineError

pub fn is_server_error(&self) -> bool

Determine if the error is a server error. A server error should not be shown to the end user.

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Eq for EngineError

impl Error for EngineError

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.

impl PartialEq for EngineError

fn eq(&self, other: &EngineError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
