Module script::script_runtime
source Β· Expand description
The script runtime contains common traits and structs commonly used by the script thread, the dom, and the worker threads.
Structs§
- A compile-time marker that there are operations that could trigger a JS garbage collection operation within the current stack frame. It is trivially copyable, so it should be passed as a function argument and reused when calling other functions whenever possible. Since it is only meaningful within the current stack frame, it is impossible to move it to a different thread or into a task that will execute asynchronously.
- A version of the
JSContext
that can be used from other threads and is thusSend
andSync
. This should only ever expose operations that are marked as thread-safe by the SpiderMonkey API, ie ones that only atomic fields in JSContext.
Enums§
- Common messages used to control the event loops in both the script and the worker
Constants§
- GC_CYCLE_START π
- GC_SLICE_START π
- THREAD_ACTIVE π
Statics§
- JOB_QUEUE_TRAPS π
- JS_ENGINE π
- SECURITY_CALLBACKS π
Traits§
- A cloneable interface for communicating with an event loop.
- An interface for receiving ScriptMsg values in an event loop. Used for synchronous DOM APIs that need to abstract over multiple kinds of event loops (worker/main thread) with different Receiver interfaces.
