Struct ContextNamespace 

pub struct ContextNamespace { /* private fields */ }

Thin resolver for scoped context partitions under one namespace root.

Phase 1 supports opening exactly one partition from a complete selector. The returned value is today’s ContextStore, preserving existing per-context behavior while putting each selector in a physically separate Lance dataset.

Implementations

impl ContextNamespace

pub async fn create( root_uri: impl Into<String>, partition_spec: PartitionSpec, ) -> LanceResult<Self>

Create or open a namespace root with default context-store options.

pub async fn create_with_options( root_uri: impl Into<String>, partition_spec: PartitionSpec, context_options: ContextStoreOptions, ) -> LanceResult<Self>

Create or open a namespace root with explicit context-store options.

pub fn new( root_uri: impl Into<String>, partition_spec: PartitionSpec, context_options: ContextStoreOptions, ) -> LanceResult<Self>

Build a namespace resolver without touching storage.

pub fn root_uri(&self) -> &str

pub fn partition_spec(&self) -> &PartitionSpec

pub fn manifest_uri(&self) -> String

pub fn resolve_partition( &self, selector: &PartitionSelector, ) -> LanceResult<PartitionInfo>

Resolve a complete selector to its opaque partition dataset URI.

pub async fn context( &self, selector: &PartitionSelector, ) -> LanceResult<ContextStore>

Open one partition as a normal ContextStore.

pub async fn partitions(&self) -> LanceResult<Vec<PartitionInfo>>

List partition mappings currently recorded in __manifest.
