# egg-mode
Twitter library for Rust 
[Documentation](https://docs.rs/egg-mode/)
This is a library for interacting with Twitter from Rust. You can see how much of the Public API is
available in the file [TODO.md]. In addition to eventually implementing the entire Public API, an
explicit goal for egg-mode is to make it as easy as possible for a client of this library to
interact with the Twitter API. Parts of this library are added as a convenience on top of the API
mechanisms; for example, cursored lists of users and tweets can be used as an iterator in addition
to being able to manually load a page at a time.
From `v0.14`, egg-mode uses the `async/await` syntax and therefore requires Rust **v1.39.0+**.
[TODO.md]: https://github.com/QuietMisdreavus/twitter-rs/blob/master/TODO.md
**NOTE**: Previous versions of egg-mode contained a port of twitter-text to use for character
counting and mention/hashtag/url extraction. That has since been extracted into its own crate,
[egg-mode-text].

To start using this library, put the following into your Cargo.toml:
```TOML
[dependencies]
egg-mode = "0.14.0"
```
By default, `egg-mode` uses `native-tls` for encryption, but also supports `rustls`.
This may be helpful if you wish to avoid linking against `OpenSSL`.
To enable, modify your `Cargo.toml` entry:
```
egg-mode = { version = "0.14", features = ["hyper-rustls"], default-features = false }
```
See available methods and tips to get started in the [Documentation][].
To authenticate a user and request an access token:
```rust
// NOTE: this assumes you are running inside an `async` function
let con_token = egg_mode::KeyPair::new("consumer key", "consumer secret");
// "oob" is needed for PIN-based auth; see docs for `request_token` for more info
let request_token = egg_mode::request_token(&con_token, "oob").await.unwrap();
let auth_url = egg_mode::authorize_url(&request_token);
// give auth_url to the user, they can sign in to Twitter and accept your app's permissions.
// they'll receive a PIN in return, they need to give this to your application
let verifier = "123456"; //read the PIN from the user here
// note this consumes con_token; if you want to sign in multiple accounts, clone it here
let (token, user_id, screen_name) =
egg_mode::access_token(con_token, &request_token, verifier).await.unwrap()
// token can be given to any egg_mode method that asks for a token
// user_id and screen_name refer to the user who signed in
```
As the last line shows, this also returns the User ID and username of the user that authenticated
with your application. With this access token, all of the other Twitter functions become available.
With this token in hand, you can get a user's profile information like this:
```rust
let rustlang = egg_mode::user::show("rustlang", &token).await.unwrap();
println!("{} (@{})", rustlang.name, rustlang.screen_name);
```
For more examples of how to use this library, check the files in the examples folder. The
authentication code for most of them is in `examples/common/mod.rs`, though that's also mostly
wrapped up in code to write the access token to disk and load it back in. `examples/bearer.rs` is an
example of using application-only authentication to get a Bearer token and use it to load a user's
posts. Other examples showcase a handful of actions from their related module. To run any of the
examples for yourself, see the notes in `examples/common/mod.rs`.
