Struct D34Shards 

pub struct D34Shards;

The D34 shard map. Fan-outs and head/packmap co-location are permanent storage contracts; changing them would strand existing rows.

Trait Implementations

impl Clone for D34Shards

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for D34Shards

impl Debug for D34Shards

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

Formats the value using the given formatter.

impl Default for D34Shards

fn default() -> Self

Returns the “default value” for a type.

impl Eq for D34Shards

impl PartialEq for D34Shards

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl ShardMap for D34Shards

fn ref_shard(&self, repo: &RepoId, ref_name: &str) -> Partition

The ref shard of ref_name: its head, replay records and quota counters. A branch head and its packmap MUST map to the same shard, so an AdvanceRefs commits in one batch.

fn coordinator(&self, ns: &NamespaceKey) -> Partition

The namespace coordinator: configuration and the grant epoch.

fn ref_index(&self, repo: &RepoId, ref_name: &str) -> Partition

The ref-name index shard that holds ref_name.

fn ref_index_partitions(&self, repo: &RepoId) -> Vec<Partition>

Every ref-name index shard of repo, in bucket order.

fn membership(&self, repo: &RepoId, pack: &BlobKey) -> Partition

The membership shard of pack.

fn object_index(&self, repo: &RepoId, object: &Hash) -> Partition

The repository-scoped index shard for an object id.
