Struct SteamWrapper 

#[non_exhaustive]
pub struct SteamWrapper {
    pub target_dir: PathBuf,
    pub loader: LoaderKind,
}

What a caller needs to install the wrapper script for a Linux native Steam launch, carried by LaunchPlan::steam_wrapper when that combination applies.

Steam’s launch options are a single fixed %command% string, so a file must sit between Steam and the game; LaunchPlan::program alone cannot express that. Neither write_wrapper_script nor steam_launch_options needs anything from here — both take only a path, because the script names no target and the options string names no loader. This type is what tells a caller the wrapper is required at all.

The wrapper is written once and never rewritten: it resolves its target at run time from WRAPPER_TARGET_FLAG, which launch_plan_in has already appended to LaunchPlan::args whenever it populates this field. A caller spawns the plan as computed and the correct target follows automatically, so the launch-options string a user pasted stays valid across every target.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

target_dir: PathBuf

The target directory the wrapper chainloads from, which reaches it as a run-time argument already present in LaunchPlan::args. Reported here so a caller can display or log it, not because the wrapper needs writing for it.

loader: LoaderKind

The loader this target injects through, reported for display and logging.

No longer feeds steam_launch_options, which dropped its WINEDLLOVERRIDES and with it the need for a loader. proxy_dll still maps this to a DLL name for a caller setting up a Wine prefix by hand.
