Struct Runtime 

pub struct Runtime { /* private fields */ }

A wrapper for the JSContext structure in SpiderMonkey.

Implementations

impl Runtime

pub fn get() -> Option<NonNull<JSContext>>

Get the JSContext for this thread.

pub fn thread_safe_js_context(&self) -> ThreadSafeJSContext

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

pub fn new(engine: JSEngineHandle) -> Runtime

Creates a new JSContext.

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 unsafe fn create_with_parent(parent: ParentRuntime) -> Runtime

Creates a new JSContext with a parent runtime. If the parent does not outlive the new runtime, its destructor will assert.

Unsafety: 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.

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: HandleObject<'_>, script: &str, rval: MutableHandleValue<'_>, options: CompileOptionsWrapper, ) -> Result<(), ()>

pub fn new_compile_options( &self, filename: &str, line: u32, ) -> CompileOptionsWrapper

Trait Implementations

impl Drop for Runtime

fn drop(&mut self)

Executes the destructor for this type.

impl Traceable for Runtime

unsafe fn trace(&self, _: *mut JSTracer)

Trace self.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
