Function create 

pub fn create(
    index_path: &str,
    metadata: &[Value],
    doc_ids: &[i64],
) -> Result<usize>

Create a new SQLite metadata database, replacing any existing one.

Each element in metadata is a JSON object representing a document’s metadata. The _subset_ column is automatically added as the primary key.

Arguments

• index_path - Path to the index directory
• metadata - Slice of JSON objects, one per document

Returns

Number of rows inserted

Errors

Returns an error if:

• The index directory cannot be created
• Column names are invalid (SQL injection prevention)
• Database operations fail

Example

use next-plaid::filtering;
use serde_json::json;

let metadata = vec![
    json!({"name": "Alice", "age": 30}),
    json!({"name": "Bob", "age": 25, "city": "NYC"}),
];
let doc_ids: Vec<i64> = (0..2).collect();

filtering::create("my_index", &metadata, &doc_ids)?;
