Enum Partitions

pub enum Partitions {
    UniformPartitions(u64),
    PartitionAtKeys(ExplicitPartitions),
}

Either one of the following partitions options can be specified

Variants

UniformPartitions(u64)

Enable uniform partitioning using given partitions count. The first components of primary key must have Uint32/Uint64 type.

PartitionAtKeys(ExplicitPartitions)

Explicitly specify key values which are used as borders for created partitions.

Implementations

impl Partitions

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

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<Partitions>, 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 Partitions

fn clone(&self) -> Partitions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Partitions

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Partitions

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Partitions

fn eq(&self, other: &Partitions) -> 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 Partitions

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
