//! Gets clip information by clip ID (one or more), broadcaster ID (one only), or game ID (one only).
//! [`get-clips`](https://dev.twitch.tv/docs/api/reference#get-clips)
//!
//! # Accessing the endpoint
//!
//! ## Request: [GetClipsRequest]
//!
//! To use this endpoint, construct a [`GetClipsRequest`] with the [`GetClipsRequest::builder()`] method.
//!
//! ```rust, no_run
//! use twitch_api2::helix::clips::get_clips;
//! let request = get_clips::GetClipsRequest::builder()
//!     .broadcaster_id("1234".to_string())
//!     .build();
//! ```
//!
//! ## Response: [Clip]
//!
//! Send the request to receive the response with [`HelixClient::req_get()`](helix::HelixClient::req_get).
//!
//! ```rust, no_run
//! use twitch_api2::helix::{self, clips::get_clips};
//! # use twitch_api2::client;
//! # #[tokio::main]
//! # async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync + 'static>> {
//! # let client: helix::HelixClient<'static, client::DummyHttpClient> = helix::HelixClient::default();
//! # let token = twitch_oauth2::AccessToken::new("validtoken".to_string());
//! # let token = twitch_oauth2::UserToken::from_existing(twitch_oauth2::dummy_http_client, token, None, None).await?;
//! let request = get_clips::GetClipsRequest::builder()
//!     .broadcaster_id("1234".to_string())
//!     .build();
//! let response: Vec<get_clips::Clip> = client.req_get(request, &token).await?.data;
//! # Ok(())
//! # }
//! ```
//!
//! You can also get the [`http::Request`] with [`request.create_request(&token, &client_id)`](helix::RequestGet::create_request)
//! and parse the [`http::Response`] with [`request.parse_response(&request.get_uri()?)`](helix::RequestGet::parse_response())
