Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

group_id: GroupId

The group identifier.

Supported API versions: 0

member_id: StrBytes

The member id generated by the coordinator. The member id must be kept during the entire lifetime of the member.

Supported API versions: 0

member_epoch: i32

The current member epoch; 0 to join the group; -1 to leave the group; -2 to indicate that the static member will rejoin.

Supported API versions: 0

instance_id: Option<StrBytes>

null if not provided or if it didn’t change since the last heartbeat; the instance Id otherwise.

Supported API versions: 0

rack_id: Option<StrBytes>

null if not provided or if it didn’t change since the last heartbeat; the rack ID of consumer otherwise.

Supported API versions: 0

rebalance_timeout_ms: i32

-1 if it didn’t change since the last heartbeat; the maximum time in milliseconds that the coordinator will wait on the member to revoke its partitions otherwise.

Supported API versions: 0

subscribed_topic_names: Option<Vec<TopicName>>

null if it didn’t change since the last heartbeat; the subscribed topic names otherwise.

Supported API versions: 0

server_assignor: Option<StrBytes>

null if not used or if it didn’t change since the last heartbeat; the server side assignor to use otherwise.

Supported API versions: 0

topic_partitions: Option<Vec<TopicPartitions>>

null if it didn’t change since the last heartbeat; the partitions owned by the member.

Supported API versions: 0

unknown_tagged_fields: BTreeMap<i32, Bytes>

The derive_builder::Builder type for this protocol item.

fn builder() -> Self::Builder

Retrieve the builder for this protocol item.

impl Clone for ConsumerGroupHeartbeatRequest

fn clone(&self) -> ConsumerGroupHeartbeatRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConsumerGroupHeartbeatRequest

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

Formats the value using the given formatter.

impl Decodable for ConsumerGroupHeartbeatRequest

fn decode<B: ByteBuf>(buf: &mut B, version: i16) -> Result<Self, DecodeError>

Decode the message from the provided buffer and version.

impl Default for ConsumerGroupHeartbeatRequest

fn default() -> Self

Returns the “default value” for a type.

impl Encodable for ConsumerGroupHeartbeatRequest

fn encode<B: ByteBufMut>( &self, buf: &mut B, version: i16, ) -> Result<(), EncodeError>

Encode the message into the target buffer.

fn compute_size(&self, version: i16) -> Result<usize, EncodeError>

Compute the total size of the message when encoded.

impl From<ConsumerGroupHeartbeatRequest> for RequestKind

fn from(value: ConsumerGroupHeartbeatRequest) -> RequestKind

impl Message for ConsumerGroupHeartbeatRequest

const VERSIONS: VersionRange = _

The valid versions for this message.

const DEPRECATED_VERSIONS: Option<VersionRange> = None
