tui-file-explorer 0.3.0

//! Default colour palette used by the file-explorer widget.
//!
//! Every constant is `pub` so that downstream crates can reference the same
//! values when building complementary widgets.
//!
//! For full visual customisation pass a [`Theme`] to [`crate::render_themed`]
//! instead of the zero-argument [`crate::render`].
//!
//! ## Named presets
//!
//! A collection of well-known editor / terminal themes is available as
//! associated constructors on [`Theme`]:
//!
//! ```no_run
//! use tui_file_explorer::Theme;
//!
//! let t = Theme::grape();
//! let t = Theme::catppuccin_mocha();
//! let t = Theme::tokyo_night();
//! let t = Theme::gruvbox_dark();
//!
//! // Or iterate the full catalogue (name, description, theme):
//! for (name, desc, _theme) in Theme::all_presets() {
//!     println!("{name} — {desc}");
//! }
//! ```
