Enum Partitioning

pub enum Partitioning {
    MessageGroupId(String),
    PartitionId(i64),
    PartitionWithGeneration(PartitionWithGeneration),
}

Option for setting order on messages. If neither is set, no guarantees on ordering or partitions to write to.

Variants

MessageGroupId(String)

All messages with given pair (producer_id, message_group_id) go to single partition in order of writes.

PartitionId(i64)

Explicit partition id to write to.

PartitionWithGeneration(PartitionWithGeneration)

Explicit partition location to write to.

Implementations

impl Partitioning

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<Partitioning>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext, ) -> Result<(), DecodeError>

where B: Buf,

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for Partitioning

fn clone(&self) -> Partitioning

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Partitioning

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Partitioning

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Partitioning

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Partitioning

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
