twitch_api 0.7.2

//! Returns a list of channels (users who have streamed within the past 6 months) that match the query via channel name or description either entirely or partially.
//!
//! [`search-channels`](https://dev.twitch.tv/docs/api/reference#search-channels)
//!
//! # Accessing the endpoint
//!
//! ## Request: [SearchChannelsRequest]
//!
//! To use this endpoint, construct a [`SearchChannelsRequest`] with the [`SearchChannelsRequest::query()`] method.
//!
//! ```rust
//! use twitch_api::helix::search::search_channels;
//! let request = search_channels::SearchChannelsRequest::query("hello");
//! ```
//!
//! ## Response: [Channel]
//!
//! Send the request to receive the response with [`HelixClient::req_get()`](helix::HelixClient::req_get).
//!
//! ```rust, no_run
//! use twitch_api::helix::{self, search::search_channels};
//! # use twitch_api::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 = search_channels::SearchChannelsRequest::query("hello");
//! let response: Vec<search_channels::Channel> = 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 [`SearchChannelsRequest::parse_response(None, &request.get_uri(), response)`](SearchChannelsRequest::parse_response)
