//! Utility functions for various telemetry-related tasks.

/// Displays a possibly long list of items to a length limited list of items.
///
/// ### Examples
/// ```
/// use re_perf_telemetry::to_short_str;
///
/// let long_list = [1, 2, 3, 4, 5];
/// let max_len = 3;
/// let result = to_short_str(long_list, max_len);
/// assert_eq!(result, "[1,2,3,..]");
///
/// let long_list = [1, 2];
/// let max_len = 3;
/// let result = to_short_str(long_list, max_len);
/// assert_eq!(result, "[1,2]");
///
/// let long_list: [u8; 0] = [];
/// let max_len = 3;
/// let result = to_short_str(long_list, max_len);
/// assert_eq!(result, "[]");
///
/// let long_list = [1, 2, 3, 4, 5];
/// let max_len = 0;
/// let result = to_short_str(long_list, max_len);
/// assert_eq!(result, "[..]");
/// ```
