Struct ThreadSafeJSContext 

Source 
pub struct ThreadSafeJSContext(/* private fields */);
Expand description

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.

Implementations§

Source§

impl ThreadSafeJSContext

Source

pub fn request_interrupt_callback(&self)

Call JS_RequestInterruptCallback from the SpiderMonkey API. This is thread-safe according to https://searchfox.org/mozilla-central/rev/7a85a111b5f42cdc07f438e36f9597c4c6dc1d48/js/public/Interrupt.h#19

Source

pub fn request_interrupt_callback_can_wait(&self)

Call JS_RequestInterruptCallbackCanWait from the SpiderMonkey API. This is thread-safe according to https://searchfox.org/mozilla-central/rev/7a85a111b5f42cdc07f438e36f9597c4c6dc1d48/js/public/Interrupt.h#19
