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.

throttle_time_ms: i32

The duration in milliseconds for which the request was throttled due to a quota violation, or zero if the request did not violate any quota.

Supported API versions: 3-12

brokers: IndexMap<BrokerId, MetadataResponseBroker>

Each broker in the response.

Supported API versions: 0-12

cluster_id: Option<StrBytes>

The cluster ID that responding broker belongs to.

Supported API versions: 2-12

controller_id: BrokerId

The ID of the controller broker.

Supported API versions: 1-12

topics: IndexMap<TopicName, MetadataResponseTopic>

Each topic in the response.

Supported API versions: 0-12

cluster_authorized_operations: i32

32-bit bitfield to represent authorized operations for this cluster.

Supported API versions: 8-10

unknown_tagged_fields: BTreeMap<i32, Bytes>

Trait Implementations

impl Builder for MetadataResponse

type Builder = MetadataResponseBuilder

The derive_builder::Builder type for this protocol item.

fn builder() -> Self::Builder

Retrieve the builder for this protocol item.

impl Clone for MetadataResponse

fn clone(&self) -> MetadataResponse

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataResponse

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

Formats the value using the given formatter.

impl Decodable for MetadataResponse

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

Decode the message from the provided buffer and version.

impl Default for MetadataResponse

fn default() -> Self

Returns the “default value” for a type.

impl Encodable for MetadataResponse

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 HeaderVersion for MetadataResponse

fn header_version(version: i16) -> i16

Maps a header version to a given version for a particular API message.

impl Message for MetadataResponse

const VERSIONS: VersionRange = _

The valid versions for this message.

const DEPRECATED_VERSIONS: Option<VersionRange> = None

The deprecated versions for this message.

impl PartialEq for MetadataResponse

fn eq(&self, other: &MetadataResponse) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
