lance-namespace

Lance Namespace Core APIs for managing namespaces and tables.

Overview

This crate provides the core APIs and trait definitions for Lance namespaces, including:

LanceNamespace trait - The main interface for namespace operations
Schema conversion utilities for Arrow schemas
Models and APIs for namespace operations (via lance-namespace-reqwest-client)

Note: For actual namespace implementations (REST, Directory, etc.), see the lance-namespace-impls crate.

Features

The namespace API supports:

Creating and managing namespaces
Creating and managing tables within namespaces
Listing namespaces and tables
Schema management
Multiple backend implementations (REST, directory-based, etc.)

Usage

rust

use lance_namespace::LanceNamespace;

// For implementations, use lance-namespace-impls:
// use lance_namespace_impls::connect;
// let namespace = connect("rest", properties).await?;
// let namespace = connect("dir", properties).await?;

// Then use the trait methods:
async fn example(namespace: &dyn LanceNamespace) {
    // List tables in the namespace
    let tables = namespace.list_tables(Default::default()).await;
}
