Enum 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.

Variants

OdbcError(DiagnosticRecord, &'static str)

DatumAccessError(DatumAccessError)

FromRowError(Box<dyn Error>)

UnexpectedNumberOfRows(&'static str)

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)>

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.
