}

What a serializer, a resolver or a transport reports. Each variant is the exception of the same name in the upstream code.

Variants

Bson(BsonException)

BsonException: what the BSON serializer itself rejects.

EndOfStream

EndOfStreamException: the document or the stream ended inside a value.

InvalidOperation(String)

InvalidOperationException.

InvalidCast(String)

InvalidCastException: a deserialized value is not of the type of the property it belongs to.

KeyNotFound(String)

KeyNotFoundException: an identifier or a type the resolver does not know, or an element type the reader has no type for.

Argument(String)

ArgumentException and ArgumentOutOfRangeException.

Overflow(String)

OverflowException.

Format(String)

FormatException.

NullReference

NullReferenceException.

Io(Arc<Error>)

IOException and SocketException: what a stream or a socket reported.

Handler(String)

A handler of an event panicked: the port’s form of an exception thrown by a handler, with the message of the panic.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

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, f: &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 From<BsonException> for Error

fn from(e: BsonException) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
