Struct IndexManifest 

pub struct IndexManifest {
    pub space_id: u64,
    pub index_id: u64,
    pub generation: IndexGeneration,
    pub shards: Vec<IndexShard>,
}

The persisted routing table for one immutable index generation.

Fields

space_id: u64

Logical namespace of this index. Index IDs are schema-local, so the pair (space_id, index_id) is the physical native-index identity.

index_id: u64

generation: IndexGeneration

shards: Vec<IndexShard>

Implementations

impl IndexManifest

pub fn new( space_id: u64, index_id: u64, generation: IndexGeneration, shards: Vec<IndexShard>, ) -> Result<IndexManifest, StorageError>

pub fn validate(&self) -> Result<(), StorageError>

pub fn route_key(&self, key: &[u8]) -> Option<&IndexShard>

Route key to its owning shard via binary search over the sorted, contiguous shard ranges.

pub fn select_shards(&self, selector: &PartitionSelector) -> Vec<&IndexShard>

pub fn scan_ranges_with_shard( &self, selector: &PartitionSelector, query_lower: &[u8], query_upper: &[u8], ) -> Vec<(u32, Vec<u8>, Vec<u8>)>

pub fn store(&self, path: &Path) -> Result<(), StorageError>

pub fn load(path: &Path) -> Result<IndexManifest, StorageError>

pub fn with_checksums(&self) -> Result<IndexManifest, StorageError>

Returns a clone with checksums computed from checkpoint files.
