Enum odbc_iter::DataAccessError

pub enum DataAccessError {
    OdbcError(DiagnosticRecord, &'static str),
    DatumAccessError(DatumAccessError),
    FromRowError(Box<dyn Error>),
    UnexpectedNumberOfRows(&'static str),
}

Errors related to data access of query result set.

This error can happen when iterating rows of executed query result set. For convenience this error can be converted into QueryError.

Trait Implementations

impl Debug for DataAccessError

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

Formats the value using the given formatter.

impl Display for DataAccessError

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

Formats the value using the given formatter.

impl Error for DataAccessError

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 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<DataAccessError> for QueryError

fn from(err: DataAccessError) -> QueryError

Performs the conversion.

impl From<DatumAccessError> for DataAccessError

fn from(err: DatumAccessError) -> DataAccessError

Performs the conversion.

impl From<ErrorContext<DiagnosticRecord, &'static str>> for DataAccessError

fn from(err: ErrorContext<DiagnosticRecord, &'static str>) -> DataAccessError

Performs the conversion.
