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.

topics: Option<Vec<MetadataRequestTopic>>

The topics to fetch metadata for.

Supported API versions: 0-12

allow_auto_topic_creation: bool

If this is true, the broker may auto-create topics that we requested which do not already exist, if it is configured to do so.

Supported API versions: 4-12

include_cluster_authorized_operations: bool

Whether to include cluster authorized operations.

Supported API versions: 8-10

include_topic_authorized_operations: bool

Whether to include topic authorized operations.

Supported API versions: 8-12

unknown_tagged_fields: BTreeMap<i32, Bytes>

Other tagged fields

Trait Implementations

impl Builder for MetadataRequest

type Builder = MetadataRequestBuilder

The derive_builder::Builder type for this protocol item.

fn builder() -> Self::Builder

Retrieve the builder for this protocol item.

impl Clone for MetadataRequest

fn clone(&self) -> MetadataRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataRequest

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

Formats the value using the given formatter.

impl Decodable for MetadataRequest

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

Decode the message from the provided buffer and version.

impl Default for MetadataRequest

fn default() -> Self

Returns the “default value” for a type.

impl Encodable for MetadataRequest

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 MetadataRequest

fn header_version(version: i16) -> i16

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

impl Message for MetadataRequest

const VERSIONS: VersionRange = _

The valid versions for this message.

const DEPRECATED_VERSIONS: Option<VersionRange> = _

The deprecated versions for this message.

impl PartialEq for MetadataRequest

fn eq(&self, other: &MetadataRequest) -> 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.

impl Request for MetadataRequest

const KEY: i16 = 3i16

The API key of this request.

type Response = MetadataResponse

The response associated with this request.

impl StructuralPartialEq for MetadataRequest
