Enum AnyBackend 

pub enum AnyBackend {
    GitWorktree(GitWorktreeBackend),
    Reflink(RefLinkBackend),
    Overlay(OverlayBackend),
    Copy(CopyBackend),
}

A concrete backend selected at runtime based on platform capabilities and configuration. Dispatches to the appropriate implementation.

Using an enum (rather than Box<dyn WorkspaceBackend>) avoids dynamic dispatch and keeps the Error associated type monomorphic.

Variants

GitWorktree(GitWorktreeBackend)

Git worktree backend — always available.

Reflink(RefLinkBackend)

Reflink (CoW) backend — requires a CoW-capable filesystem.

Overlay(OverlayBackend)

OverlayFS backend — Linux only.

Copy(CopyBackend)

Plain recursive-copy backend — universal fallback.

Implementations

impl AnyBackend

pub fn from_kind(kind: BackendKind, root: PathBuf) -> Result<Self>

Construct the appropriate backend for the resolved (non-Auto) kind and repo root.

If kind is BackendKind::Auto (which should be resolved before calling this function), falls back to GitWorktree.

Errors

Returns an error if the overlay backend is selected but is not supported on this platform (not Linux, or no mount strategy available).

Trait Implementations

impl WorkspaceBackend for AnyBackend

type Error = AnyBackendError

The error type returned by backend operations.

fn create( &self, name: &WorkspaceId, epoch: &EpochId, ) -> Result<WorkspaceInfo, Self::Error>

Create a new workspace.

fn destroy(&self, name: &WorkspaceId) -> Result<(), Self::Error>

Destroy a workspace.

fn list(&self) -> Result<Vec<WorkspaceInfo>, Self::Error>

List all workspaces.

fn status(&self, name: &WorkspaceId) -> Result<WorkspaceStatus, Self::Error>

Get the current status of a workspace.

fn snapshot(&self, name: &WorkspaceId) -> Result<SnapshotResult, Self::Error>

Capture all changes in the workspace.

fn workspace_path(&self, name: &WorkspaceId) -> PathBuf

Get the absolute path to a workspace.

fn exists(&self, name: &WorkspaceId) -> bool

Check if a workspace exists.
