Struct LocalConcurrentModificationError 

pub struct LocalConcurrentModificationError { /* private fields */ }

Concurrent modification error — the consumer was accessed from more than one task.

Corresponds to Java’s java.util.ConcurrentModificationException, thrown by KafkaConsumer.acquire() (“KafkaConsumer is not safe for multi-threaded access”). A plain RuntimeException, so no predicate holds for it.

Implementations

impl LocalConcurrentModificationError

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

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

Keeps the plain name under CLAUDE.md §2, for consistency with kafka_error_type! — see the note on this macro about the constructors these classes deliberately do not model. (Deliberately not an intra-doc link: this doc comment expands into each declaring module, where that macro is not in scope.)

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

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

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

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 LocalConcurrentModificationError

fn clone(&self) -> LocalConcurrentModificationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocalConcurrentModificationError

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

Formats the value using the given formatter.

impl Display for LocalConcurrentModificationError

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

Formats the value using the given formatter.

impl Error for LocalConcurrentModificationError

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.
