Enum SettingsError 

pub enum SettingsError {
    Missing(StoreId),
    Corrupt(Box<dyn Error + Send + Sync>),
    WrongStore {
        expected: StoreId,
        actual: StoreId,
    },
    NotRegularFile(StoreId),
    File(FileError),
    Bug(Bug),
}

Missing, damaged or unreadable store settings remain distinct errors.

Variants

Missing(StoreId)

The store has no settings file.

Corrupt(Box<dyn Error + Send + Sync>)

The settings do not contain the declared data.

WrongStore

A settings file belongs to a different directory’s store.

Fields

expected: StoreId

The id naming the directory.

actual: StoreId

The id in the settings file.

NotRegularFile(StoreId)

The settings path is not an ordinary file, or is a symbolic link.

File(FileError)

Reading or writing settings failed at the filesystem boundary.

Bug(Bug)

Reading or writing settings panicked: a bug, which the caller reports (E15).
