Struct CreateShardKey 

pub struct CreateShardKey {

Fields

shard_key: Option<ShardKey>

User-defined shard key

shards_number: Option<u32>

Number of shards to create per shard key

replication_factor: Option<u32>

Number of replicas of each shard to create

placement: Vec<u64>

List of peer ids, allowed to create shards. If empty - all peers are allowed

initial_state: Option<i32>

Initial state of created replicas. Warning: use with care.

Implementations

impl CreateShardKey

pub fn shards_number(&self) -> u32

Returns the value of shards_number, or the default value if shards_number is unset.

pub fn replication_factor(&self) -> u32

Returns the value of replication_factor, or the default value if replication_factor is unset.

pub fn initial_state(&self) -> ReplicaState

Returns the enum value of initial_state, or the default if the field is unset or set to an invalid enum value.

pub fn set_initial_state(&mut self, value: ReplicaState)

Sets initial_state to the provided enum value.

Trait Implementations

impl Clone for CreateShardKey

fn clone(&self) -> CreateShardKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreateShardKey

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

Formats the value using the given formatter.

impl Default for CreateShardKey

fn default() -> Self

Returns the “default value” for a type.

impl Hash for CreateShardKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for CreateShardKey

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

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

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for CreateShardKey

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