Enum LineageError 

pub enum LineageError {
    Missing {
        path: PathBuf,
    },
    NotAnArchive {
        path: PathBuf,
    },
    Archived {
        path: PathBuf,
    },
    Mismatch {
        expected: LineageId,
        actual: LineageId,
    },
}

Why a store’s lineage does not permit a read or write.

Variants

Missing

A store has no lineage row, so its writable history cannot be identified.

Fields

path: PathBuf

Inspected database.

NotAnArchive

A restore forks a new writable lineage, so its source must be a sealed backup archive: an interrupted copy of an archive stays sealed, while one of a live store would be a writable file sharing that store’s lineage.

Fields

path: PathBuf

Live store named as the restore source.

Archived

A backup archive is read and verified, never written.

Fields

path: PathBuf

Archive the write targeted.

Mismatch

The store continues a different writable history than the caller observed.

Fields

expected: LineageId

Lineage the caller observed.

actual: LineageId

Lineage of the store.

Trait Implementations

impl Debug for LineageError

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

Formats the value using the given formatter.

impl Display for LineageError

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

Formats the value using the given formatter.

impl Error for LineageError

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<LineageError> for StoreError

fn from(source: LineageError) -> Self

Converts to this type from the input type.
