Struct SerializationError

pub struct SerializationError(/* private fields */);

An error indicating that a failure happened during serialization.

The error is type-erased so that the crate users can define their own serialization impls and their errors. As for the impls defined or generated by the driver itself, the following errors can be returned:

• row::BuiltinSerializationError is returned when serialization of one of types with an impl built into the driver fails. It is also returned from impls generated by the SerializeRow macro.
• value::BuiltinSerializationError is analogous to the above but is returned from SerializeValue::serialize instead both in the case of builtin impls and impls generated by the SerializeValue macro. It won’t be returned by the Session directly, but it might be nested in the row::BuiltinSerializationError.

Implementations

impl SerializationError

pub fn new(err: impl Error + Send + Sync + 'static) -> SerializationError

Constructs a new SerializationError.

pub fn downcast_ref<T: Error + 'static>(&self) -> Option<&T>

Retrieve an error reason by downcasting to specific type.

Trait Implementations

impl Clone for SerializationError

fn clone(&self) -> SerializationError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SerializationError

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

Formats the value using the given formatter.

impl Display for SerializationError

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

Formats the value using the given formatter.

impl Error for SerializationError

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.
