Module script_runtime

The script runtime contains common traits and structs commonly used by the script thread, the dom, and the worker threads.

Structs

CanGc 🔒

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.

Runtime 🔒

StreamConsumer 🔒

ThreadSafeJSContext 🔒

A version of the JSContext that can be used from other threads and is thus Send and Sync. This should only ever expose operations that are marked as thread-safe by the SpiderMonkey API, ie ones that only atomic fields in JSContext.
