Implementations

impl Error

pub fn overflow(from: &str, to: &str) -> Self

Create an overflow error when a value cannot be converted to a target type.

pub fn type_mismatch(value_oid: u32, target_oid: u32) -> Self

Create a type mismatch error when encoding to an incompatible OID.

pub fn is_connection_broken(&self) -> bool

Returns true if the error indicates the connection is broken and cannot be reused.

Conservative: assumes broken unless the error is known to be safe.

pub fn sqlstate(&self) -> Option<&str>

Get the SQLSTATE code if this is a server error.

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.

impl<Src: Debug, Dst: Debug + ?Sized> From<ConvertError<AlignmentError<Src, Dst>, SizeError<Src, Dst>, Infallible>> for Error

fn from(err: CastError<Src, Dst>) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Infallible> for Error

fn from(err: Infallible) -> Self

Converts to this type from the input type.
