Struct script::script_runtime::Runtime

pub struct Runtime {
    rt: Runtime,
    pub microtask_queue: Rc<MicrotaskQueue>,
    job_queue: *mut JobQueue,
    networking_task_src: Option<Box<NetworkingTaskSource>>,
}

Fields

rt: Runtime

microtask_queue: Rc<MicrotaskQueue>

job_queue: *mut JobQueue

networking_task_src: Option<Box<NetworkingTaskSource>>

Implementations

impl Runtime

pub(crate) fn new( networking_task_source: Option<NetworkingTaskSource>, ) -> Runtime

Create a new runtime, optionally with the given NetworkingTaskSource.

Safety

If panicking does not abort the program, any threads with child runtimes will continue executing after the thread with the parent runtime panics, but they will be in an invalid and undefined state.

This, like many calls to SpiderMoney API, is unsafe.

pub(crate) unsafe fn new_with_parent( parent: Option<ParentRuntime>, networking_task_source: Option<NetworkingTaskSource>, ) -> Runtime

Create a new runtime, optionally with the given ParentRuntime and NetworkingTaskSource.

Safety

If panicking does not abort the program, any threads with child runtimes will continue executing after the thread with the parent runtime panics, but they will be in an invalid and undefined state.

The parent pointer in the ParentRuntime argument must point to a valid object in memory.

This, like many calls to the SpiderMoney API, is unsafe.

pub(crate) fn thread_safe_js_context(&self) -> ThreadSafeJSContext

Methods from Deref<Target = RustRuntime>

pub fn thread_safe_js_context(&self) -> ThreadSafeJSContext

Create a ThreadSafeJSContext that can detect when this Runtime is destroyed.

pub fn prepare_for_new_child(&self) -> ParentRuntime

Signal that a new child runtime will be created in the future, and ensure that this runtime will not allow itself to be destroyed before the new child runtime. Returns a handle that can be passed to create_with_parent in order to create a new runtime on another thread that is associated with this runtime.

pub fn rt(&self) -> *mut JSRuntime

Returns the JSRuntime object.

pub fn cx(&self) -> *mut JSContext

Returns the JSContext object.

pub fn evaluate_script( &self, glob: Handle<'_, *mut JSObject>, script: &str, filename: &str, line_num: u32, rval: MutableHandle<'_, Value>, ) -> Result<(), ()>

Trait Implementations

Dereferences the value.

impl Drop for Runtime

fn drop(&mut self)
