pub trait PurgeGoal: ExclusiveOption { }Expand description
Marker for a selected purge goal: one of PurgeAllMode,
FreeSpaceMode, RevisionCountMode, or SizeMode.
Exactly one of -a / -f / -m / -s is required, so the command can
only be assembled and spawned once CachePurge has transitioned into
one of these states.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
