Struct ShardConfig 

pub struct ShardConfig {
    pub number_of_shards: u32,
    pub mask_high: u32,
    pub mask_low: u32,
}

Precomputed configuration for shard assignment. Mirrors the Go multiShardCoordinator struct.

Fields

number_of_shards: u32

Total number of regular shards (not counting the metachain).

mask_high: u32

Bitmask using ceil(log2(number_of_shards)) bits.

mask_low: u32

Bitmask using ceil(log2(number_of_shards)) - 1 bits (fallback).

Implementations

impl ShardConfig

pub const THREE_SHARDS: ShardConfig

Pre-built configuration for the standard 3-shard setup used on MultiversX mainnet.

pub const fn new(number_of_shards: u32) -> Option<ShardConfig>

Creates a new ShardConfig for the given number of regular shards.

Returns None if number_of_shards is zero.

pub fn compute_id(&self, address: &Address) -> ShardId

Calculates the shard for a given address. Mirrors ComputeIdFromBytes in multiShardCoordinator.go.

pub fn same_shard(&self, a: &Address, b: &Address) -> bool

Returns true if both addresses belong to the same shard. Mirrors SameShard in multiShardCoordinator.go.

Trait Implementations

impl Clone for ShardConfig

fn clone(&self) -> ShardConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShardConfig

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

Formats the value using the given formatter.

impl PartialEq for ShardConfig

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