Enum BootError 

pub enum BootError {
    NotInitialised(PathBuf),
    Store(StoreError),
    Instantiate(InstantiateError),
    Engine(EngineError),
}

Errors surfaced by [Engine::from_workspace_root] (lean) and its full counterpart (memstead_git_branch::engine_from_workspace_root).

The boot path layers three error sources: layout detection, workspace-store load failures, per-mount backend instantiation (folder + archive vs git-branch), and engine construction (duplicate-mem checks). #[from] lifts the lower-layer types so callers branch on a single error envelope.

Variants

NotInitialised(PathBuf)

detect_layout returned crate::Layout::Empty — workspace root has no recognised layout marker. Operator runs memstead mem-repo init rather than booting against an empty directory.

Store(StoreError)

Underlying crate::WorkspaceStoreAdapter load failed (missing config file, parse error, format-mismatch).

Instantiate(InstantiateError)

Per-mount backend instantiation failed. Today: a mount declared MountStorage::GitBranch while the lean boot path only knows folder + archive.

Engine(EngineError)

Engine construction failed (duplicate mem names, etc.).

Trait Implementations

impl Debug for BootError

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

Formats the value using the given formatter.

impl Display for BootError

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

Formats the value using the given formatter.

impl Error for BootError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
