twitch_api2 0.6.1

//! Get information about all predictions or specific predictions for a Twitch channel. Prediction information is available for 90 days.
//! [`get-predictions`](https://dev.twitch.tv/docs/api/reference#get-predictions)
//!
//! ## Request: [GetPredictionsRequest]
//!
//! To use this endpoint, construct a [`GetPredictionsRequest`] with the [`GetPredictionsRequest::builder()`] method.
//!
//! ```rust
//! use twitch_api2::helix::predictions::get_predictions;
//! let request = get_predictions::GetPredictionsRequest::builder()
//!     .id(vec!["ed961efd-8a3f-4cf5-a9d0-e616c590cd2a".into()])
//!     .broadcaster_id("1234")
//!     .build();
//! ```
//!
//! ## Response: [Prediction]
//!
//! Send the request to receive the response with [`HelixClient::req_get()`](helix::HelixClient::req_get).
//!
//! ```rust, no_run
//! use twitch_api2::helix::{self, predictions::get_predictions};
//! # 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(&client, token, None, None).await?;
//! let request = get_predictions::GetPredictionsRequest::builder()
//!     .id(vec!["ed961efd-8a3f-4cf5-a9d0-e616c590cd2a".into()])
//!     .broadcaster_id("1234")
//!     .build();
//! let response: Vec<get_predictions::Prediction> = 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 [`GetPredictionsRequest::parse_response(None, &request.get_uri(), response)`](GetPredictionsRequest::parse_response)
