StatementNotAllowed(String)

A top-level statement was not allowed, usually because of an AllowedStatements restriction

Tuple Fields of StatementNotAllowed

0: String

FunctionNotAllowed(String)

Tuple Fields of FunctionNotAllowed

0: String

InvalidFunctionName(String)

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for Error

fn from(error: Error) -> Self

Performs the conversion.
