Struct ThreadPoolInner

struct ThreadPoolInner {
    job_count: Mutex<usize>,
    empty_condvar: Condvar,
}

Internal data structure for tracking the current job status. This is shared by worker closures via Arc so that the workers can report to the pool that it started/finished a job.

Fields

job_count: Mutex<usize>

empty_condvar: Condvar

Implementations

impl ThreadPoolInner

fn start_job(&self)

Increment the job count.

fn finish_job(&self)

Decrement the job count.

fn wait_empty(&self)

Wait until the job count becomes 0.

NOTE: We can optimize this function by adding another field to ThreadPoolInner, but let’s not care about that in this homework.

Trait Implementations

impl Debug for ThreadPoolInner

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