Struct ordered_locks::LockToken

source · [−]

pub struct LockToken<'a, L: Level>(_);

Expand description

While this exists only locks with a level higher than L, may be locked. These tokens are carried around the call stack to indicate tho current locking level. They have no size and should disappear at runtime.

Implementations
