// Tauri plugin - pedantic/nursery lints relaxed
#![allow(clippy::pedantic)]
#![allow(clippy::nursery)]

//! # tauri-plugin-velesdb
//!
//! A Tauri plugin for `VelesDB` - Vector search in desktop applications.
//!
//! This plugin provides seamless integration of `VelesDB`'s vector database
//! capabilities into Tauri desktop applications.
//!
//! ## Features
//!
//! - **Collection Management**: Create, list, and delete vector collections
//! - **Vector Operations**: Insert, update, and delete vectors with payloads
//! - **Vector Search**: Fast similarity search with multiple distance metrics
//! - **Text Search**: BM25 full-text search across payloads
//! - **Hybrid Search**: Combined vector + text search with RRF fusion
//! - **`VelesQL`**: SQL-like query language for advanced searches
//!
//! ## Usage
//!
//! ### Rust (Plugin Registration)
//!
//! ```rust,ignore
//! fn main() {
//!     tauri::Builder::default()
//!         .plugin(tauri_plugin_velesdb::init("./data"))
//!         .run(tauri::generate_context!())
//!         .expect("error while running tauri application");
//! }
//! ```
//!
//! ### JavaScript (Frontend)
//!
//! ```javascript
//! import { invoke } from '@tauri-apps/api/core';
//!
//! // Create a collection
//! await invoke('plugin:velesdb|create_collection', {
//!   request: { name: 'documents', dimension: 768, metric: 'cosine' }
//! });
//!
//! // Insert vectors
//! await invoke('plugin:velesdb|upsert', {
//!   request: {
//!     collection: 'documents',
//!     points: [{ id: 1, vector: [...], payload: { title: 'Doc' } }]
//!   }
//! });
//!
//! // Search
//! const results = await invoke('plugin:velesdb|search', {
//!   request: { collection: 'documents', vector: [...], topK: 10 }
//! });
//! ```
