//! Helpers to test if a specific preview style is enabled or not.
//!
//! The motivation for these functions isn't to avoid code duplication but to ease promoting preview styles
//! to stable. The challenge with directly using [`is_preview`](PyFormatContext::is_preview) is that it is unclear
//! for which specific feature this preview check is for. Having named functions simplifies the promotion:
//! Simply delete the function and let Rust tell you which checks you have to remove.
