ReadOnlyOpenError

Enum ReadOnlyOpenError

pub enum ReadOnlyOpenError {
    Local(CovenError),
    Storage(SyncError),
    Bug(Bug),
}

Expand description

Opening a read-only store or its saved file-storage connection failed.

Variants§

Local(CovenError)

The database or store directory could not be opened.

Storage(SyncError)

Saved settings, credential custody or provider construction failed.

Bug(Bug)

Opening panicked: a bug, which the caller reports (E15).
