Struct Job 

pub struct Job { /* private fields */ }

a background job: count items of f on the workers; wake() when it is finished

Implementations

impl Job

pub fn new() -> Job

pub fn set( &mut self, count: u64, f: impl Fn(usize, &JobCtl) + Send + Sync + 'static, ) -> bool

the work of the next start: count items of f (false while the job runs)

pub fn set_count(&mut self, count: u64) -> bool

another item count for the same function (false while the job runs)

pub fn start(&self) -> bool

run it in the background; false: it is still running [thr_job_start]

pub fn wait(&self) -> Result<(), Cancelled>

block until the job is finished (this thread helps with items not taken yet)

pub fn cancel(&self)

skip the items not started yet; the job still finishes (wake)

pub fn done(&self) -> bool

finished (or never started)

pub fn items_done(&self) -> u64

pub fn count(&self) -> u64

Trait Implementations

impl Default for Job

fn default() -> Self

Returns the “default value” for a type.

impl Drop for Job

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
