A unified error enum that contains several errors that might occurr during the lifecycle of this driver

Variants

Io

An error occurred when performing I/O to the server.

Fields

kind: IoErrorKind

A list specifying general categories of I/O error.

message: String

The error description.

Protocol(Cow<'static, str>)

An error happened during the request or response parsing.

Encoding(Cow<'static, str>)

Server responded with encoding not supported.

Conversion(Cow<'static, str>)

Conversion failure from one type to another.

Utf8

Tried to convert data to UTF-8 that was not valid.

Utf16

Tried to convert data to UTF-16 that was not valid.

ParseInt(ParseIntError)

Tried to parse an integer that was not an integer.

Server(TokenError)

An error returned by the server.

Tls(String)

An error in the TLS handshake.

Gssapi(String)

Available on Unix and crate feature integrated-auth-gssapi only.

An error from the GSSAPI library.

SspiRs(String)

Available on Unix and crate feature sspi-rs only.

An error from the sspi (sspi-rs) library.

Routing

Server requested a connection to an alternative address.

Fields

host: String

The requested hostname

port: u16

The requested port.

BulkInput(Cow<'static, str>)

Invalid input in Bulk Upload

Implementations

impl Error

pub fn is_deadlock(&self) -> bool

True, if the error was caused by a deadlock.

pub fn code(&self) -> Option<u32>

Returns the error code, if the error originates from the server.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 Eq for Error

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
