pub trait LockBefore<X> { }
Expand description

Marker trait that indicates that Self is an ancestor of X.

Functions and trait impls that want to apply lock ordering bounds should use this instead of LockAfter. Types should prefer to implement LockAfter instead of this trait. Like From and Into, a blanket impl of LockBefore is provided for all types that implement LockAfter
