Enum KrafkaError 

#[non_exhaustive]
pub enum KrafkaError {
    Network(Arc<Error>),
    Protocol {
        message: String,
    },
    Auth {
        message: String,

    Serialization {

The main error type for Krafka operations.

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.

Network(Arc<Error>)

Network-related errors (connection, I/O).

Wrapped in Arc so that cloning preserves the full error chain (including raw_os_error() and source()).

Protocol

Protocol encoding/decoding errors.

Fields

message: String

Error message describing the protocol error.

Auth

Authentication errors.

Fields

message: String

Error message describing the authentication failure.

Timeout

Timeout errors.

Fields

operation: String

The operation that timed out.

Broker

Broker errors returned by Kafka.

Fields

code: ErrorCode

The Kafka error code.

message: String

Human-readable error message.

Config

Configuration errors.

Fields

message: String

Error message describing the configuration problem.

Compression

Compression errors.

Fields

message: String

Error message describing the compression failure.

InvalidState

Invalid state errors.

Fields

message: String

Error message describing the invalid state.

Serialization

Serialization errors.

Fields

message: String

Error message describing the serialization failure.

SchemaRegistry

Schema registry errors.

Fields

message: String

Human-readable error message.

Trait Implementations

impl Clone for KrafkaError

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 KrafkaError

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

Formats the value using the given formatter.

impl Display for KrafkaError

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

Formats the value using the given formatter.

impl Error for KrafkaError

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

🔬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 KrafkaError

fn from(err: Error) -> Self

Converts to this type from the input type.
