Struct WorkHost 

pub struct WorkHost { /* private fields */ }

Cloneable process-owned host for live work handles.

Rust Hara values are currently evaluator-thread values (Rc, not Send). The host therefore schedules work cooperatively on that evaluator thread. Submission only enqueues; polling or waiting on the result Promise, or an explicit WorkHost::run, advances the run.

Implementations

impl WorkHost

pub fn new() -> Self

pub fn submit<F>(&self, id: Option<&str>, task: F) -> Result<WorkRun, String>

where F: FnOnce() -> Result<Value, String> + 'static,

Submit work without executing it inline.

pub fn submit_rejection<F>( &self, id: Option<&str>, task: F, ) -> Result<WorkRun, String>

where F: FnOnce() -> Result<Value, PromiseRejection> + 'static,

Submit work whose executor already returns a native structured rejection.

pub fn submit_scoped<F>( &self, options: WorkOptions, task: F, ) -> Result<WorkRun, String>

where F: FnOnce(WorkContext) -> Result<Value, String> + 'static,

pub fn submit_scoped_rejection<F>( &self, options: WorkOptions, task: F, ) -> Result<WorkRun, String>

where F: FnOnce(WorkContext) -> Result<Value, PromiseRejection> + 'static,

pub fn resolve(&self, reference: &str) -> Result<WorkRun, String>

Resolve a live handle from a portable raw identifier.

pub fn resolve_id(&self, id: &WorkId) -> Result<WorkRun, String>

pub fn run(&self, id: &WorkId) -> bool

Run one queued item by ID. Returns false when no runnable item remains.

pub fn run_next(&self) -> bool

pub fn drain(&self)

pub fn status(&self) -> WorkHostStatus

pub fn started(&self) -> bool

pub fn start(&self)

pub fn stop(&self)

pub fn kill(&self)

pub fn same_identity(&self, other: &Self) -> bool
