Trait Implementations

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.

impl PartialEq<MetadataRequest> 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.
