This week's crate is wgpu, a cross-platform graphics and compute library based on WebGPU.

Despite a lack of suggestions, llogiq is pleased with his choice.

Please submit your suggestions and votes for next week!

Calls for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization.

If you are a feature implementer and would like your RFC to appear in this list, add a call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

No calls for testing were issued this week by Rust, Rust language RFCs or Rustup.*

Let us know if you would like your feature to be tracked as a part of this list.

Meilisearch – search engine API bringing AI-powered hybrid search

Laravel 9 Scout Full Text Search with Algolia Tutorial

A full-text search feature in a web application is incredibly useful for users to navigate through content-rich web and mobile applications, as demonstrated in this Laravel Scout full text search tutorial. This thorough guide will show you how to use the Laravel Scout algolia module to deeply integrate full-text search into a Laravel application. To create a full-text search using Laravel Scout Algolia, we will gradually lift the veil on each step that must be shared; Because of Laravel Scout, adding or using Algolia in Laravel has become really simple. The robust scout package provided by Laravel Scout enhances the integration of full-text search right into your model. A straightforward driver-based solution for adding full-text search functionality to your Eloquent models is provided by Laravel Scout. Scout automatically keeps your search indexes in sync with your Eloquent records by using model observers. Although Scout already provides drivers for Algolia and MeiliSearch, building custom drivers has never been simple, even though you are free to freely extend Scout with your own own search implementations.

Laravel 9 Algolia Full Text Search Example

- Create New Laravel Project - Update Database Details in ENV - Install Laravel Scout & Algolia Packages - Set Up Algolia in Laravel - Set Up Model and Migration - Set Up Controller - Create Routes - Configure Blade View - Run Laravel Project

Create New Laravel Project

First, enter the console, type the following command, and then correctly execute the command to install the new Laravel app. If the app has already been created, ignore the following command. composer create-project --prefer-dist laravel/laravel laravel-demo Enter the app's folder after it has been created: cd laravel-demo

Update Database Details in ENV

The database name, username, and password must then be entered in the .env configuration file. DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=database_name DB_USERNAME=database_user_name DB_PASSWORD=database_password

Install Laravel Scout & Algolia Packages

Using the composer tool, we must now install the laravel scout and algolia search dependencies; these packages are necessary to create instant search functionality in laravel. Let's use the laravel scout package installation command. composer require laravel/scout The Scout configuration file should be published using the vendor: We have introduced the Scout library to Laravel; let's let Laravel know that it exists as well. publish the artisan order. The scout.php configuration file will be published to the config directory of your application when the following command is executed: php artisan vendor:publish --provider="LaravelScoutScoutServiceProvider" Next, make the following change to the .env file's line of code. SCOUT_QUEUE=true Execute the following command to add the Laravel package for the Algolia search client. composer require algolia/algoliasearch-client-php

Set Up Algolia in Laravel

In order to obtain the API keys in this section, we must visit the Algolia website and register. Algolia not only provides excellent UX for the web and e-commerce apps, but also AI-powered search & discovery across websites & apps. You must go to the API Keys area and then search for the Your API Keys part on the API Keys page. In the .env configuration file, define the Application ID and Admin API keys after copying them from there. ALGOLIA_APP_ID=add_application_id ALGOLIA_SECRET=add_admin_api_key

Set Up Model and Migration

In order to add a new table to the database, this step demonstrates how to construct a Model by similarly setting up the model and running a migration. Let's use the command below to create the new Product model file. php artisan make:model Product -m Next, you must update the values in the Product table in the app/Models/Product.php file, which will be added to the database. Ideally, we also need to define the searchableAs() method and import the Scout Searchable service. Read the full article

Calls for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

RFCs

No calls for testing were issued this week.

Rust

No calls for testing were issued this week.

Rustup

No calls for testing were issued this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Call for Participation; projects and speakers

CFP - Projects

Quote of the Week

... opaque number sequences (\<GitHub> "issue numbers") are not very informative about what is behind that pointer, and pretending they are is harmful. People could provide, instead, actual reasons for things, which do not require dereferencing random pointers, which thrashes cache.

– Jubilee on rust-internals
