Internet Game Database API crate. With the igdb crate, you can retrieve information on any of IGDB API endpoints.

If you would like to help the project, pull requests and suggestions are always welcome :)

Installation

This crate is using cargo-features so your project compiles only code related to the endpoint you'll be using. For example, if you're querying only games and characters endpoint, Cargo.toml should look like this:

[dependencies]
rusty_igdb = { "2.0.0", default-features = false, features = ["game", "character"]}

Unless you want the entire codebase from the crate containing all endpoits methods and structs add this to your Cargo.toml:

[dependencies]
rusty_igdb = "2.0.0"

Also, this package uses rust nightly build. Be sure to have installed.

Usage

Basic Rust usage

IGDB requires Twitch access credentials to work.

You can read how to retrieve those credentials here. With Twitch Access Token and Twitch Client ID in hands, we can bring IGDB API wrapper into scope like this:

// Along with the wrapper, bring the endpoint Structs to scope so your code knows the return type of the Vector
use rusty_igdb::{ APIWrapper, models::{ Game, GameResult, Character, CharacterResult  } };
use std::env;

fn main() {
  // Using stored environment variables to unwrap our credentials
  let access_token = env::var("TWITCH_ACCESS_TOKEN").unwrap();
  let client_id = env::var("TWITCH_CLIENT_ID").unwrap();

  // Authenticating with our API wrapper
  let api_wrapper = APIWrapper::new(&access_token, &client_id).unwrap();

  // Using the API wrapper methods to query for Zelda games
  // Here we are expecting a vector of Game struct, so we used the imported Struct.
  let zelda_games: GameResult = api_wrapper
    .build("games") // endpoint
    .search("zelda")
    .limit("2")
    .fields("name")
    .request()
    .unwrap();

  // Using the API wrapper methods to query for Characters named Mario
  // Here we are expecting a vector of Character struct.
  let characters_named_mario: CharacterResult = api_wrapper
    .build("characters") // endpoint
    .search("mario")
    .fields("name")
    .request()
    .unwrap();
}

This example used environment variables to store the Twitch retrieved credentials, and then accessing with the rust standard feature std::env. In your personal project, you can manage these credentials as you please.

You can avoid typing fields() query method if you want a full fields response This would return all fields related to characters that contains Solid Snake

  // no .fields() query method returns every field from endpoint
  let solid_snake_chars_vec: CharacterResult = api_wrapper
    .build("characters")
    .search("Solid Snake")
    .request()
    .unwrap();

JSON response

The crate offers a JSON public method, so you can customize the response content into your project. Value represents the serde_json::Value struct in the below example. See the serde_json crate for more information about.

All IGDB endpoints should be available using the request_json() method.

    let test_characters: Vec<Value> = api_wrapper
      .build("search")
      .fields("name, gender, country_name")
      .where_like("gender != null")
      .limit("2")
      .request_json()
      .unwrap();
    
    /*
    response should look like this:
      [{
        "gender": 0,
        "id": 4445,
        "name": "Beast"
      },
      {
        "gender": 0,
        "id": 8988,
        "name": "Mr. Wong"
      }],
    */

The result should look and accessed like this:

      [{
        "gender": 0,
        "id": 4445,
        "name": "Beast"
      },
      {
        "gender": 0,
        "id": 8988,
        "name": "Mr. Wong"
      }]

  let first_character = &test_characters[0]["gender"];

Roadmap

• Remaining IGDB Endpoints (see milestone)
• Add code coverage
