Enum CredentialPersistence 

#[non_exhaustive]
pub enum CredentialPersistence {
    EntryOnly,
    ProcessOnly,
    UntilLogout,
    UntilReboot,
    UntilDelete,
    Unspecified,
}

A descriptor for the lifetime of stored credentials, returned from a credential store’s persistence call.

This enum may change even in minor and patch versions of the library, so it’s marked as non-exhaustive.

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.

EntryOnly

Credential storage is in the entry, so storage vanishes when the entry is dropped.

ProcessOnly

Credential storage is in process memory, so storage vanishes when the process terminates

UntilLogout

Credential storage is in user-space memory, so storage vanishes when the user logs out

UntilReboot

Credentials stored in kernel-space memory, so storage vanishes when the machine reboots

UntilDelete

Credentials stored on disk, so storage vanishes when the credential is deleted

Unspecified

Placeholder for cases not (yet) handled here
