#[repr(u32)]pub enum PrepareFailureReason {
Internal = 0,
OutOfSpace = 1,
UnsupportedDowngrade = 2,
}
Expand description
The set of values provided when an installation attempt fails on [State.prepare
].
Variants§
Internal = 0
The prepare failed because of some other reason.
OutOfSpace = 1
The prepare failed because the system does not have enough space to fetch the update package.
UnsupportedDowngrade = 2
The prepare failed because the system cannot downgrade across a version boundary. Not all unsupported downgrades will fail with this error – just the ones the system can detect. For more context, see RFC-0071.
