Struct LockToken

Source 
pub struct LockToken<'a, L: Level>(/* private fields */);
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§

Source

pub fn downgrade<LC: Higher<L>>(&mut self) -> LockToken<'_, LC>
