Available on crate feature experimental-sliding-sync only.

Internal representation of errors in Sliding Sync.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BadResponse(String)

The response we’ve received from the server can’t be parsed or doesn’t match up with the current expectations on the client side. A sync-restart might be required.

ResponseAlreadyReceived

Fields

pos: Option<String>

The position that has been received.

The response we’ve received from the server has already been received in the past because it has a pos that we have recently seen.

RequestGeneratorHasNotBeenInitialized(String)

A SlidingSyncListRequestGenerator has been used without having been initialized. It happens when a response is handled before a request has been sent. It usually happens when testing.

InvalidRange

Fields

start: u32

Start bound.

end: u32

End bound.

Ranges have a start bound greater than end.

UnauthenticatedUser

We tried to read the user id of a client but it was missing.

InternalChannelIsBroken

The internal channel of SlidingSync seems to be broken.

InvalidSlidingSyncIdentifier

The name of the Sliding Sync instance is too long.

JoinError

Fields

task_description: String

Task description.

error: JoinError

The original JoinError.

A task failed to execute to completion.

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)>

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
