Enum DeserError 

#[non_exhaustive]
pub enum DeserError {
    Malformed {
        reason: String,
    },
    SchemaUnavailable {
        reason: String,
    },
    NotReady {
        reason: String,
    },
}

A payload could not be deserialized.

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.

Malformed

The payload bytes do not match the expected format.

Fields

reason: String

Human-readable cause, for logs and dead-record metrics.

SchemaUnavailable

A schema required to decode the payload is not available.

Fields

reason: String

Human-readable cause.

NotReady

The payload cannot be decoded yet: a required resource (typically a schema fetched from a registry) is still being obtained, and the deserializer has already triggered the asynchronous work that will make it available. The chain reports the batch Blocked at this payload and the driver’s retry loop re-pushes it — the record is neither dropped nor counted as an error, and the stage’s ErrorPolicy does not apply.

Contract: a deserializer must return this before emitting any record for the payload; records emitted ahead of a NotReady would be duplicated when the payload is replayed.

Fields

reason: String

What is being waited for.

Trait Implementations

impl Debug for DeserError

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

Formats the value using the given formatter.

impl Display for DeserError

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

Formats the value using the given formatter.

impl Error for DeserError

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.
