Implementations

impl ShardLayout

pub fn v0_single_shard() -> Self

pub fn v0(num_shards: NumShards, version: ShardVersion) -> Self

Return a V0 Shardlayout

pub fn v1( boundary_accounts: Vec<AccountId>, shards_split_map: Option<Vec<Vec<ShardId>>>, version: ShardVersion, ) -> Self

Return a V1 Shardlayout

pub fn v0_test() -> Self

Returns a V0 ShardLayout. It is only used in tests

pub fn get_children_shards_uids( &self, parent_shard_id: ShardId, ) -> Option<Vec<ShardUId>>

Given a parent shard id, return the shard uids for the shards in the current shard layout that are split from this parent shard. If this shard layout has no parent shard layout, return None

pub fn get_children_shards_ids( &self, parent_shard_id: ShardId, ) -> Option<Vec<ShardId>>

Given a parent shard id, return the shard ids for the shards in the current shard layout that are split from this parent shard. If this shard layout has no parent shard layout, return None

pub fn get_parent_shard_id( &self, shard_id: ShardId, ) -> Result<ShardId, ShardLayoutError>

Return the parent shard id for a given shard in the shard layout Only calls this function for shard layout that has parent shard layouts Returns error if shard_id is an invalid shard id in the current layout Panics if self has no parent shard layout

pub fn version(&self) -> ShardVersion

pub fn shard_ids(&self) -> impl Iterator<Item = ShardId>

pub fn shard_uids(&self) -> impl Iterator<Item = ShardUId> + '_

Returns an iterator that iterates over all the shard uids for all the shards in the shard layout

Trait Implementations

impl Clone for ShardLayout

fn clone(&self) -> ShardLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShardLayout

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ShardLayout

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ShardLayout

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

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 ShardLayout
