//! Updates the broadcaster’s chat settings.
//!
//! Only rewards created programmatically by the same client_id can be updated.
//! [`update-chat-settings`](https://dev.twitch.tv/docs/api/reference#update-chat-settings)
//!
//! # Accessing the endpoint
//!
//! ## Request: [UpdateChatSettingsRequest]
//!
//! To use this endpoint, construct an [`UpdateChatSettingsRequest`] with the [`UpdateChatSettingsRequest::builder()`] method.
//!
//! ```rust
//! use twitch_api2::helix::chat::update_chat_settings;
//! let request = update_chat_settings::UpdateChatSettingsRequest::builder()
//!     .broadcaster_id("1234")
//!     .moderator_id("5678")
//!     .build();
//! ```
//!
//! ## Body: [UpdateChatSettingsBody]
//!
//! We also need to provide a body to the request containing what we want to change.
//!
//! ```
//! # use twitch_api2::helix::chat::update_chat_settings;
//! let body = update_chat_settings::UpdateChatSettingsBody::builder()
//!     .slow_mode(true)
//!     .slow_mode_wait_time(10)
//!     .build();
//! ```
//!
//! ## Response: [ChatSettings]
//!
//!
//! Send the request to receive the response with [`HelixClient::req_patch()`](helix::HelixClient::req_patch).
//!
//!
//! ```rust, no_run
//! use twitch_api2::helix::{self, chat::update_chat_settings};
//! # 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 = update_chat_settings::UpdateChatSettingsRequest::builder()
//!     .broadcaster_id("1234")
//!     .moderator_id("5678")
//!     .build();
//! let body = update_chat_settings::UpdateChatSettingsBody::builder()
//!     .slow_mode(true)
//!     .slow_mode_wait_time(10)
//!     .build();
//! let response: helix::chat::ChatSettings = client.req_patch(request, body, &token).await?.data;
//! # Ok(())
//! # }
//! ```
//!
//! You can also get the [`http::Request`] with [`request.create_request(&token, &client_id)`](helix::RequestPost::create_request)
//! and parse the [`http::Response`] with [`UpdateChatSettingsRequest::parse_response(None, &request.get_uri(), response)`](UpdateChatSettingsRequest::parse_response)
