Enum PrepareError

#[non_exhaustive]
pub enum PrepareError {
    ConnectionPoolError(ConnectionPoolError),
    AllAttemptsFailed {
        first_attempt: RequestAttemptError,
    },
    PreparedStatementIdsMismatch,
}

An error returned by Session::prepare().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ConnectionPoolError(ConnectionPoolError)

Failed to find a node with working connection pool.

AllAttemptsFailed

Failed to prepare statement on every connection from the pool.

Fields

first_attempt: RequestAttemptError

PreparedStatementIdsMismatch

Prepared statement id mismatch.

Trait Implementations

impl Clone for PrepareError

fn clone(&self) -> PrepareError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrepareError

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

Formats the value using the given formatter.

impl Display for PrepareError

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

Formats the value using the given formatter.

impl Error for PrepareError

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.
