//! Create a single scheduled broadcast or a recurring scheduled broadcast for a channel’s [stream schedule](https://help.twitch.tv/s/article/channel-page-setup#Schedule).
//! [`create-channel-stream-schedule-segment`](https://dev.twitch.tv/docs/api/reference#create-channel-stream-schedule-segment)
//!
//! # Accessing the endpoint
//!
//! ## Request: [CreateChannelStreamScheduleSegmentRequest]
//!
//! To use this endpoint, construct a [`CreateChannelStreamScheduleSegmentRequest`] with the [`CreateChannelStreamScheduleSegmentRequest::broadcaster_id()`] method.
//!
//! ```rust
//! use twitch_api::helix::schedule::create_channel_stream_schedule_segment;
//! let request =
//!     create_channel_stream_schedule_segment::CreateChannelStreamScheduleSegmentRequest::broadcaster_id("141981764");
//! ```
//!
//! ## Body: [CreateChannelStreamScheduleSegmentBody]
//!
//! We also need to provide a body to the request containing what we want to change.
//!
//! ```
//! # use std::convert::TryFrom;
//! # use twitch_api::helix::schedule::create_channel_stream_schedule_segment;
//! let mut body =
//!     create_channel_stream_schedule_segment::CreateChannelStreamScheduleSegmentBody::new(
//!         twitch_api::types::Timestamp::try_from("2021-07-01T18:00:00Z").unwrap(),
//!         "America/New_York",
//!         false,
//!     );
//! body.duration = Some("60".into());
//! body.category_id = Some(twitch_types::CategoryIdRef::from_static("509670").as_cow());
//! body.title = Some("TwitchDev Monthly Update // July 1, 2021".into());
//! ```
//!
//! ## Response: [ScheduledBroadcasts]
//!
//!
//! Send the request to receive the response with [`HelixClient::req_post()`](helix::HelixClient::req_post).
//!
//!
//! ```rust, no_run
//! use twitch_api::helix::{self, schedule::create_channel_stream_schedule_segment};
//! # use twitch_api::client;
//! # use std::convert::TryFrom;
//! # #[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 =
//!     create_channel_stream_schedule_segment::CreateChannelStreamScheduleSegmentRequest::broadcaster_id("141981764");
//! let timestamp = twitch_api::types::Timestamp::try_from("2021-07-01T18:00:00Z")?;
//! let mut body =
//!     create_channel_stream_schedule_segment::CreateChannelStreamScheduleSegmentBody::new(
//!         twitch_api::types::Timestamp::try_from("2021-07-01T18:00:00Z").unwrap(),
//!         "America/New_York",
//!         false,
//!     );
//! body.duration = Some("60".into());
//! body.category_id = Some(twitch_types::CategoryIdRef::from_static("509670").as_cow());
//! body.title = Some("TwitchDev Monthly Update // July 1, 2021".into());
//! let response: create_channel_stream_schedule_segment::CreateChannelStreamScheduleSegmentResponse = client.req_post(request, body, &token).await?.data;
//! # Ok(())
//! # }
//! ```
//!
//! You can also get the [`http::Request`] with [`request.create_request(&body, &token, &client_id)`](helix::RequestPost::create_request)
//! and parse the [`http::Response`] with [`CreateChannelStreamScheduleSegmentRequest::parse_response(None, &request.get_uri(), response)`](CreateChannelStreamScheduleSegmentRequest::parse_response)
