+//! # Sonic Channel
+//! Rust client for [sonic] search backend.
+//! 
+//! 
+//! ## Example usage
+//! 
+//! ### Search channel
+//! 
+//! ```rust
+//! use sonic_channel::*;
+//! 
+//! fn main() -> result::Result<()> {
+//!     let channel = SonicChannel::connect_with_start(
+//!         ChannelMode::Search,
+//!         "localhost:1491",
+//!         "SecretPassword",
+//!     )?;
+//! 
+//!     let objects = channel.query("collection", "bucket", "recipe")?;
+//!     dbg!(objects);
+//! 
+//!     Ok(())
+//! }
+//! ```
+//! 
+//! ### Ingest channel
+//! 
+//! ```rust
+//! use sonic_channel::*;
+//! 
+//! fn main() -> result::Result<()> {
+//!     let mut channel = SonicChannel::connect_with_start(
+//!         ChannelMode::Ingest,
+//!         "localhost:1491",
+//!         "SecretPassword",
+//!     )?;
+//! 
+//!     let pushed = channel.push("collection", "bucket", "object:1", "my best recipe")?;
+//!     // or
+//!     // let pushed = channel.push_with_locale("collection", "bucket", "object:1", "Мой лучший рецепт", "rus")?;
+//!     dbg!(pushed);
+//! 
+//!     Ok(())
+//! }
