mangadex-api 4.2.1

//! Builder for the OAuth login endpoint.
//!
//! <https://api.mangadex.org/docs/02-authentication/>
//!
//! It's the support for [Personal Client](https://api.mangadex.org/docs/02-authentication/personal-clients/)
//!
//! # Examples
//!
//! ```rust
//! use mangadex_api_types::{Password, Username};
//! use mangadex_api::v5::MangaDexClient;
//! use mangadex_api_schema::v5::oauth::ClientInfo;
//!
//! # async fn run() -> anyhow::Result<()> {
//!
//! let mut client = MangaDexClient::default();
//!
//! client.set_client_info(&ClientInfo {
//!     client_id: "someClientId".to_string(),
//!     client_secret: "someClientSecret".to_string()
//! }).await?;
//!
//! // Login to your account
//!
//! let login_res = client
//!     .oauth()
//!     .login()
//!     .username(Username::parse("myusername")?)
//!     .password(Password::parse("hunter2")?)
//!     .send()
//!     .await?;
//!
//! println!("login: {:?}", login_res);
//!
//! // Wait until the access token expires
//! tokio::time::sleep(tokio::time::Duration::from_secs(<usize as TryInto<u64>>::try_into(login_res.expires_in)?)).await;
//!
//! let refresh_res = client
//!     .oauth()
//!     .refresh()
//!     .send()
//!     .await?;
//!
//! println!("refresh: {:?}", refresh_res);
