Implementations

impl RuntimeLayer

pub fn prepare( game_root: &Path, runtime_base: &Path, run_id: &str, ) -> Result<Self>

Create a fresh owned layer. Existing directories and locations inside the source installation are refused, never adopted or overwritten.

pub fn redirect_unicode_cache(&self, cache: &Path) -> Result<()>

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

pub fn retain(&mut self) -> Result<PathBuf>

Player games keep running when the launching manager exits. Their layer is retained with an ownership marker, and never swept as a test session.

pub fn retain_after<T>( &mut self, start: impl FnOnce(&Path) -> Result<T>, ) -> Result<T>

Mark the layer before starting a player, then commit retention only when startup and its bookkeeping succeed. On error the caller must stop any child it started; dropping this layer then removes the failed preparation.

Trait Implementations

impl Drop for RuntimeLayer

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
