Enum StoreError 

pub enum StoreError {
    NotInitialised {
        path: PathBuf,
    },
    Io {
        path: PathBuf,
        source: Error,
    },
    Parse {
        path: PathBuf,
        message: String,
    },
    FormatMismatch {
        path: PathBuf,
        expected: String,
        found: String,
    },
    LegacyLayout {
        path: PathBuf,
        found: String,
    },
    Other(String),
}

Errors surfaced by WorkspaceStoreAdapter::load and WorkspaceStoreAdapter::save_state. Backend-specific failures surface as StoreError::Other with a string message; structured per-adapter errors can extend the enum later.

Variants

NotInitialised

Workspace root has no .memstead/ directory or no recognised adapter file inside it. Distinct from Io so callers can distinguish “needs memstead init” from “permissions broke”.

Fields

path: PathBuf

Io

IO failure reading or writing one of the adapter files.

Fields

path: PathBuf

source: Error

Parse

TOML or JSON parse / serialise failure. The wrapped string is the underlying serde error; the file is named so operators know where to look.

Fields

path: PathBuf

message: String

FormatMismatch

Format version mismatch — adapter understands a different schema version than the file declares.

Fields

path: PathBuf

expected: String

found: String

LegacyLayout

Pre-rename workspace layout. The unit-noun cut renamed every on-disk shape with no dual-read; refusing keeps an old workspace from booting empty, half-mounted, or silently rewritten. The message names the one-shot migration steps.

Fields

path: PathBuf

found: String

Other(String)

Catch-all for adapter-specific failures. Carries an agent-readable message; structured variants extend the enum.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<StoreError> for BootError

fn from(source: StoreError) -> Self

Converts to this type from the input type.

impl From<StoreError> for PipelineEditError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
