Enum tor_persist::Error

#[non_exhaustive]
pub enum Error {
    IoError(Arc<Error>),
    Permissions(Error),
    NoLock,
    Serialize(Arc<Error>),
    Deserialize(Arc<Error>),
}

An error manipulating persistent state.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IoError(Arc<Error>)

An IO error occurred.

Permissions(Error)

Permissions on a file or path were incorrect

NoLock

Tried to save without holding an exclusive lock.

Serialize(Arc<Error>)

Problem when serializing JSON data.

Deserialize(Arc<Error>)

Problem when deserializing JSON data.
