Struct InstallData 

pub struct InstallData { /* private fields */ }

Installation-specific paths and identifiers.

Contains all the data that varies between different installation types of the same game (Steam vs Epic, Windows vs Linux, etc.).

Path Relativity

Important: All paths in this struct are RELATIVE paths, either to:

• The game’s root directory (most paths)
• The data directory (vanilla_packs)

This allows the same configuration to work across different installation locations by combining with the actual game path at runtime.

Implementations

impl InstallData

pub fn vanilla_packs(&self) -> &Vec<String>

Vanilla PackFile names (without paths).

Used as fallback when no manifest file exists (Empire, Napoleon). Paths are relative to the data_path.

pub fn use_manifest(&self) -> &bool

Whether to use the game’s manifest file for vanilla PackFile discovery.

true: Read manifest file (most games) false: Use hardcoded vanilla_packs list

pub fn store_id(&self) -> &u64

Steam/store ID for the game.

Used for Steam integration and auto-detection.

pub fn store_id_ak(&self) -> &u64

Steam/store ID for the game’s Assembly Kit.

0 if no Assembly Kit is available on Steam.

pub fn executable(&self) -> &String

Game executable file name (with extension).

Used to detect installation type and for launching the game. Examples: "Warhammer3.exe", "Shogun2.exe"

pub fn data_path(&self) -> &String

Data directory path relative to game root.

Where PackFiles are stored. Usually "data" but varies.

pub fn language_path(&self) -> &String

Language file directory path relative to game root.

Where language.txt or equivalent is located. May be different from data_path on Linux builds.

pub fn local_mods_path(&self) -> &String

Local mods directory path relative to game root.

Where the game loads locally-installed mods from.

pub fn downloaded_mods_path(&self) -> &String

Downloaded mods directory path relative to game root.

Where Steam Workshop and other downloaded mods are stored. Empty string if the game doesn’t support downloadable mods.

pub fn config_folder(&self) -> &Option<String>

Config directory name (not full path).

Used with platform-specific config locations (AppData on Windows, .config on Linux). None if game doesn’t store config externally.

Trait Implementations

impl Clone for InstallData

fn clone(&self) -> InstallData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InstallData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
