Struct NotLeaderOrFollowerError 

pub struct NotLeaderOrFollowerError { /* private fields */ }

Broker returns this error if a request could not be processed because the broker is not the leader or follower for a topic partition. This could be a transient error during leader elections and reassignments. For Produce and other requests which are intended only for the leader, this error indicates that the broker is not the current leader. For consumer Fetch requests which may be satisfied by a leader or follower, this error indicates that the broker is not a replica of the topic partition.

Translation notes

Error code Errors::NotLeaderOrFollower. Java extends chain: NotLeaderOrFollowerException -> InvalidMetadataException -> RefreshRetriableException -> RetriableException -> ApiException -> KafkaException.

Implementations

impl NotLeaderOrFollowerError

pub fn new(message: impl Into<String>) -> Self

Create the error with the given message and no cause, mirroring Java’s (String message) constructor.

This keeps the plain name under CLAUDE.md §2: the dominant Java shape among the classes this macro declares is (String message) + (String message, Throwable cause), whose parameter-name intersection is {message} — matched exactly by (String message).

pub fn with_source(message: impl Into<String>, source: Error) -> Self

Create the error with the given message and an underlying cause, mirroring Java’s (String message, Throwable cause) constructor.

Suffixed with the one parameter beyond the {message} intersection (CLAUDE.md §2) — see new.

pub fn with_default_message() -> Self

Create the error with the default message for its error code, mirroring Java’s Errors.exception().

Not a constructor overload, so CLAUDE.md §2’s suffixing does not apply: it translates the Errors static factory, which fills in Errors.message() and has no Java constructor counterpart.

pub fn message(&self) -> &str

The error message.

pub fn source(&self) -> Option<&Error>

The underlying cause, if any. Mirrors Java’s getCause().

Trait Implementations

impl Clone for NotLeaderOrFollowerError

fn clone(&self) -> NotLeaderOrFollowerError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NotLeaderOrFollowerError

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

Formats the value using the given formatter.

impl Display for NotLeaderOrFollowerError

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

Formats the value using the given formatter.

impl Error for NotLeaderOrFollowerError

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
