//! The number of pending notifications in rofication-daemon
//!
//! A different color is used if there are critical notifications.
//!
//! # Configuration
//!
//! Key | Values | Default
//! ----|--------|--------
//! `interval` | Refresh rate in seconds. | `1`
//! `format` | A string to customise the output of this block. See below for placeholders. | `" $icon $num.eng(w:1) "`
//! `socket_path` | Socket path for the rofication daemon. Supports path expansions e.g. `~`. | `"/tmp/rofi_notification_daemon"`
//!
//! Placeholder | Value | Type | Unit
//! -------------|-------|------|-----
//! `icon` | A static icon | Icon | -
//! `num` | Number of pending notifications | Number | -
//!
//! # Example
//!
//! ```toml
//! [[block]]
//! block = "rofication"
//! interval = 1
//! socket_path = "/tmp/rofi_notification_daemon"
//! [[block.click]]
//! button = "left"
//! cmd = "rofication-gui"
//! ```
//!
//! # Icons Used
//! - `bell`
