Struct Job 

pub struct Job { /* private fields */ }

A background job whose items run between browser frames.

Implementations

impl Job

pub fn new() -> Self

Create an empty, completed job.

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

Replace a completed job’s work; item counts must fit wasm32 address space.

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

Replace only the item count after completion.

pub fn start(&self) -> bool

Queue the job; execution begins during the next host step.

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

Finish remaining work synchronously when a caller explicitly waits.

pub fn cancel(&self)

Request cancellation at the next item boundary.

pub fn done(&self) -> bool

Whether the job has completed or has not started.

pub fn items_done(&self) -> u64

Completed item count.

pub fn count(&self) -> u64

Total item count.

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.
