Variants

DbError(DbError, String)

Database sent a response containing some error with a message

BadQuery(BadQuery)

Caller passed an invalid query

IoError(Arc<Error>)

Input/Output error has occurred, connection broken etc.

ProtocolError(&'static str)

Unexpected message received

InvalidMessage(String)

Invalid message received

TimeoutError

Timeout error has occurred, function didn’t complete in time.

TooManyOrphanedStreamIds(u16)

UnableToAllocStreamId

RequestTimeout(String)

Client timeout occurred before any response arrived

TranslationError(TranslationError)

Address translation failed

Implementations

impl QueryError

pub fn is_address_unavailable_for_use(&self) -> bool

Checks if this error indicates that a chosen source port/address cannot be bound. This is caused by one of the following:

• The source address is already used by another socket,
• The source address is reserved and the process does not have sufficient privileges to use it.

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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.
