CopyProvider

a3s_box_runtime::rootfs

Struct CopyProvider

pub struct CopyProvider;

Expand description

Full recursive copy provider — works on all platforms.

This is the original behavior: copies the entire cached rootfs into box_dir/rootfs/. Safe but slow for large images.

Trait Implementations§

impl RootfsProvider for CopyProvider

fn prepare(&self, box_dir: &Path, cache_dir: &Path) -> Result<PathBuf>

Prepare a rootfs at box_dir from the cached read-only layer at cache_dir. Returns the path to use as InstanceSpec.rootfs_path.

fn cleanup(&self, box_dir: &Path, persistent: bool) -> Result<()>

Cleanup after box stops. Read more

fn name(&self) -> &'static str

Human-readable name for logging.
