Struct ShardConfig

pub struct ShardConfig {
    pub num_shards: u64,
    pub shard_size: u64,
    pub shard_headers: Vec<String>,
}

Shard config contains the parameters of the Sharding operation, namely:

• number of shards into which input dataset will be split,
• size of each shard, i.e., the number of rows in each shard,
• headers of columns whose rows are hashed to find the index of a shard where the corresponding row will be placed.

Fields

num_shards: u64

shard_size: u64

shard_headers: Vec<String>

headers of columns whose rows are hashed to find the index of a shard where the corresponding row will be placed

Trait Implementations

impl Clone for ShardConfig

fn clone(&self) -> ShardConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShardConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ShardConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ShardConfig

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 PartialEq for ShardConfig

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

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

const 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 ShardConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ShardConfig
