Enum LockState 

pub enum LockState {
    Unlocked,
    WriteLocked {
        owner_id: u64,
    },
    ReadLocked {
        n_readers: usize,
    },
}

File-level lock state for exclusive write access simulation.

Variants

Unlocked

No lock held.

WriteLocked

An exclusive write lock is held by owner_id.

Fields

owner_id: u64

Simulated process/thread identifier.

ReadLocked

A shared read lock is held by n_readers.

Fields

n_readers: usize

Number of concurrent readers.

Trait Implementations

impl Clone for LockState

fn clone(&self) -> LockState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LockState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LockState

fn eq(&self, other: &LockState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
