Struct LockState

Source

pub struct LockState {
    last_acquired: Option<(LockRank, &'static Location<'static>)>,
    depth: u32,
}

Available on crate feature std only.

Expand description

Per-thread state for the deadlock checker.

Fields§

§last_acquired: Option<(LockRank, &'static Location<'static>)>

The last lock we acquired, and where.

§depth: u32

The number of locks currently held.

This is used to enforce stack-like lock acquisition and release.
