Enum Error 

pub enum Error {
    UnableToRetrieveNumCols(Error),
    ColumnFailure {
        name: String,
        index: usize,
        source: ColumnFailure,
    },
    OdbcBufferTooSmall {
        max_bytes_per_batch: usize,
        bytes_per_row: usize,
    },
    EncodingInvalid {
        source: FromUtf8Error,
    },
}

A variation of things which can go wrong then creating an crate::OdbcReader.

Variants

UnableToRetrieveNumCols(Error)

Failure to retrieve the number of columns from the result set.

ColumnFailure

Indicates that the error is related to a specify column.

Fields

name: String

index: usize

source: ColumnFailure

OdbcBufferTooSmall

Failure during constructing an OdbcReader, if it turns out the buffer memory size limit is too small.

Fields

max_bytes_per_batch: usize

bytes_per_row: usize

EncodingInvalid

We expect UTF-8 to be the default on non-windows platforms. Yet still some systems are configured different.

Fields

source: FromUtf8Error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
