Module backends 

Adapters for communicating with Desktop Environments, Window Managers, and Display Servers.

Structs

AwwwBackend

Backend implementing dynamic wallpaper transitions on Wayland via awww.

DaemonConfig

Configuration for a background daemon to ensure consistent lifecycle management.

DaemonManager

A generic coordinator to handle background daemon processes.

GnomeBackend

HyprlandBackend

Backend implementing wallpaper orchestration for the Hyprland compositor via hyprpaper.

OpenboxBackend

SwaybgBackend

Backend implementing static wallpaper rendering on Wayland via swaybg.

XfceBackend

Enums

Desktop

Represents the supported Desktop Environments (DE) or Window Managers (WM). We use an Enum instead of a String to ensure type safety and prevent logic errors.

Traits

CommandExt

Extension trait for std::process::Command to unify command execution logic.

WallpaperBackend

Core trait defining the wallpaper application logic. Follows the “Functional Core, Imperative Shell” pattern.

Functions

compile_wallpapers_for_monitors

Pre-processes and compiles separate multi-picture composite backgrounds in parallel for each monitor.

detect_monitors

Detects active outputs (monitors) using a robust fallback chain with a retry loop.

get_active_xrandr_monitors

Get active X11 monitors via xrandr to filter out stale configurations.

is_process_running

Checks if a process with the specified name is currently running.

is_process_running_shared

Checks if a process is running using an existing, shared System instance.

parse_hyprland

Pure parser for Hyprland output.

parse_niri

Pure parser for Niri output.

parse_wlr_randr

Pure parser for wlr-randr output.

parse_xfce

XFCE Logic: Matches active hardware (xrandr) with XFCE properties. If a monitor is active but has no XFCE property yet, we synthesize one.

parse_xrandr

Pure parser for xrandr output.

prune_stale_xfce_configs

Prunes stale XFCE configurations that no longer correspond to active hardware.

set_wallpaper

Set desktop wallpaper based on the detected Desktop Environment.

terminate_processes_by_name

Terminates all processes that match the provided name.
