Struct ProducerBufferExhaustedError 

pub struct ProducerBufferExhaustedError { /* private fields */ }

The producer cannot allocate memory for a record because the buffer pool is full and the max blocking time has elapsed.

Corresponds to Java’s BufferExhaustedException, which lives in org.apache.kafka.clients.producer rather than common.errors.

Java extends chain: BufferExhaustedException -> TimeoutException -> RetriableException -> ApiException -> KafkaException

It is therefore retriable, and reports error code Errors::RequestTimedOut: it has no entry in Errors itself, and Java’s Errors.forException walks up the superclass chain, finding TimeoutException’s.

Implementations

impl ProducerBufferExhaustedError

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 ProducerBufferExhaustedError

fn clone(&self) -> ProducerBufferExhaustedError

Returns a duplicate of the value.

impl Error for ProducerBufferExhaustedError

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
