Enum LoadError 

pub enum LoadError {
    NotFound {
        path: PathBuf,
    },
    StaleSnapshot,
    Corrupt {
        detail: String,
    },
    PathSafety(PathSafetyError),
    Io(Error),
    AlreadyLoaded,
}

Failure modes for load_derived.

The caller should treat LoadError::NotFound as a soft miss (the derived file simply doesn’t exist yet — normal on first run) and all other variants as hard errors that warrant deleting or ignoring the derived file.

Variants

NotFound

The derived-cache file does not exist at path.

Fields

path: PathBuf

The path that was checked.

StaleSnapshot

The file’s snapshot_sha256 header field does not match snapshot_sha256.

The derived file was produced from a different graph snapshot (stale or corrupted). The file should be deleted and queries recomputed.

Corrupt

The file is structurally corrupt (bad magic, wrong version, truncated entry stream, etc.).

Fields

detail: String

Human-readable description of the corruption detected.

PathSafety(PathSafetyError)

The path failed workspace safety validation before the file was opened.

Wraps sqry_core::persistence::PathSafetyError.

Io(Error)

An IO error occurred while opening or reading the file.

AlreadyLoaded

A successful load_derived call has already been applied to this DB.

Subsequent calls are no-ops: the cold-load window is closed after the first successful load, preventing accidental double-apply of stale or different on-disk state.

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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<Error> for LoadError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<PathSafetyError> for LoadError

fn from(source: PathSafetyError) -> Self

Converts to this type from the input type.
