The general types of checkpoint error.

Variants

CpAlreadyExists

The specified checkpoint already exists.

CpDoesntExist

The specified checkpoint does not exist.

CpInUse

The specified checkpoint is in use.

Most likely to occur if checkpoint removal is attempted while a reference to the underlying data exists.

CpKeyDoesntExist

The specified checkpoint key does not exist.

Deserialize

Deserialization of checkpoint data failed.

Initialization

An initialization error occurred.

Most likely to occur when initializing storage or storage wrappers.

Integrity

An integrity check of checkpoint data failed.

InvalidIdentifier

An invalid identifier was used.

Most likely to occur when specifying a checkpoint identifier or a checkpoint key.

Io

An I/O error occurred.

Other

A checkpoint error occurred that is not covered by ErrorKind.

Serialize

Serialization of checkpoint data failed.
