meilisearch-sdk (WIP) Latest Version

MeiliSearch-sdk is an async client for MeiliSearch written in Rust. MeiliSearch is a powerful, fast, open-source, easy to use and deploy search engine. Both searching and indexing are highly customizable. Features such as typo-tolerance, filters, and synonyms are provided out-of-the-box.

Table of Contents

πŸ”§ Installation

This crate requires a MeiliSearch server to run. See here to install and run MeiliSearch.

Then, put meilisearch-sdk = "0.1" in your Cargo.toml, as usual.

Since this crate is async, you have to run your program in the tokio runtime (cf the example below). You will need tokio = { version = "0.2", features=["macros"] } in your Cargo.toml. When targetting Wasm, the browser will replace tokio.

Using this crate is possible without serde, but a lot of features require serde. Add serde = {version="1.0", features=["derive"]} in your Cargo.toml.

πŸš€ Getting Started

Here is a quickstart for a search request (please follow the installation steps before)

use meilisearch_sdk::{document::*, indexes::*, client::*, search::*};
use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
struct Book {
    book_id: usize,
    title: String,
}

// That trait is required to make a struct usable by an index
impl Document for Book {
    type UIDType = usize;

    fn get_uid(&self) -> &Self::UIDType {
        &self.book_id
    }
}

#[tokio::main]
async fn main() {
    // Create a client (without sending any request so that can't fail)
    let client = Client::new("http://localhost:7700", "");

    // Get the index called "books"
    let mut books = client.get_or_create("books").await.unwrap();

    // Add some books in the index
    books.add_documents(&[
        Book{book_id: 123,  title: String::from("Pride and Prejudice")},
        Book{book_id: 456,  title: String::from("Le Petit Prince")},
        Book{book_id: 1,    title: String::from("Alice In Wonderland")},
        Book{book_id: 1344, title: String::from("The Hobbit")},
        Book{book_id: 4,    title: String::from("Harry Potter and the Half-Blood Prince")},
        Book{book_id: 42,   title: String::from("The Hitchhiker's Guide to the Galaxy")},
    ], Some("book_id")).await.unwrap();

    // Query books (note that there is a typo)
    let query = Query::new("harry pottre");
    println!("{:?}", books.search::<Book>(&query).await.unwrap().hits);
}

Output:

[Book { book_id: 4, title: "Harry Potter and the Half-Blood Prince" }]

🌐 Running in the browser with WASM

This crate fully supports WASM. The only difference between the WASM and the native version is that the native version has one more variant (Error::Http) in the Error enum. That should not matter so much but we could add this variant in WASM too. However, making a program intended to run in a web browser requires a very different design than a CLI program. To see an example of a simple Rust web app using meilisearch, see the tutorial (not available yet).

WARNING: meilisearch-sdk will panic if no Window is available (ex: Web extension).

πŸ€– Compatibility with MeiliSearch

This crate is currently supporting MeiliSearch v11.0 and will be maintained.

Running the tests

All the tests are documentation tests. Since they are all making operations on the MeiliSearch server, running all the tests simultaneously would cause panics. To run the tests one by one, run cargo test -- --test-threads=1.
