Module boa_engine::job

Boa’s API to create and customize ECMAScript jobs and job queues.

NativeJob is an ECMAScript Job, or a closure that runs an ECMAScript computation when there’s no other computation running.

JobCallback is an ECMAScript JobCallback record, containing an ECMAScript function that is executed when a promise is either fulfilled or rejected.

JobQueue is a trait encompassing the required functionality for a job queue; this allows implementing custom event loops, custom handling of Jobs or other fun things. This trait is also accompanied by two implementors of the trait:

• IdleJobQueue, which is a queue that does nothing, and the default queue if no queue is provided. Useful for hosts that want to disable promises.
• SimpleJobQueue, which is a simple FIFO queue that runs all jobs to completion, bailing on the first error encountered.
