Trait starnix_sync::LockEqualOrBefore
source · pub trait LockEqualOrBefore<X> { }Expand description
Marker trait that indicates that Self is X or an ancestor of X.
Functions and trait impls that want to apply lock ordering bounds should
prefer LockBefore. However, there are some situations where using
template to apply lock ordering bounds is impossible, so a fixed level
must be used instead. In that case, LockEqualOrBefore can be used as
a workaround to avoid restricting other methods to just the fixed level.
See the tests for the example.
Note: Any type representing a lock level must explicitly implement
LockEqualOrBefore<X> for X (or use a lock_level macro) for this to
work.
