Enum Error 

#[non_exhaustive]
pub enum Error {
    Net(Error),
    Json(String),
    Flate(Error),
    MissingSnapshot,
    Desync,
}

Errors produced while publishing or consuming JSON.

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.

Net(Error)

An error from the underlying track.

Json(String)

A value failed to serialize, deserialize, or apply as a merge patch.

Stored as a string since serde_json::Error is not Clone.

Flate(Error)

A compressed frame could not be decoded (malformed, truncated, or oversized).

MissingSnapshot

A merge patch arrived with no snapshot to apply it to.

Every group opens with a full snapshot, so this means frames reached snapshot::Decoder out of order, or a group’s first frame was routed as a delta.

Desync

A compressed stream frame was encoded but never written, so the shared DEFLATE window is ahead of what the consumer holds and nothing later in this group can be decoded.

Unlike snapshot, a stream has no keyframe to resynchronize on, so the encoder refuses to continue rather than emit frames that cannot be read. Recover by rolling a new group and calling stream::Encoder::reset.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

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, __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 From<Error> for Error

fn from(source: Error) -> 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<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.
