Struct LockdepState 

pub(crate) struct LockdepState {
    depth: usize,
    held: [HeldLock; 6],
}

Per-CPU lockdep state, active only under cfg(debug_assertions).

Fields

depth: usize

held: [HeldLock; 6]

Implementations

impl LockdepState

pub(crate) const fn new() -> Self

pub(crate) fn acquire( &mut self, rank: LockRank, cpu: Option<usize>, caller: usize, )

Record a lock acquisition. Panics in debug if ordering is violated.

pub(crate) fn release(&mut self, rank: LockRank)

Record a lock release. Asserts LIFO order.

pub(crate) fn assert_no_scheduler_locks(&self)

Assert that no scheduler lock is held.

pub(crate) fn assert_held(&self, rank: LockRank)

Assert that a specific rank is currently held.

pub(crate) fn current_depth(&self) -> usize

Return the current depth.
