Struct Context 

pub struct Context {
    context: NonNull<JSContext>,
    rooted: RootedArena,
    order: RefCell<Vec<GCType>>,
    private: NonNull<ContextInner>,
}

Represents the thread-local state of the runtime.

Wrapper around JSContext that provides lifetime information and convenient APIs.

Fields

context: NonNull<JSContext>

rooted: RootedArena

order: RefCell<Vec<GCType>>

private: NonNull<ContextInner>

Implementations

impl Context

pub fn from_runtime(rt: &Runtime) -> Context

pub unsafe fn new_unchecked(cx: *mut JSContext) -> Context

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

pub fn get_inner_data(&self) -> NonNull<ContextInner>

pub fn get_raw_private(&self) -> *mut dyn TraceablePrivate

pub fn set_private(&self, private: Box<dyn TraceablePrivate>)

pub fn root<T: Rootable>(&self, value: T) -> Local<'_, T>

Roots a value and returns a [Local] to it. The Local is only unrooted when the [Context] is dropped

Trait Implementations

impl Drop for Context

fn drop(&mut self)

Drops the rooted values in reverse-order to maintain LIFO destruction in the Linked List.

impl<'cx> FromArgument<'_, 'cx> for &'cx Context

type Config = ()

fn from_argument( accessor: &mut Accessor<'_, 'cx>, _: (), ) -> Result<&'cx Context>

Converts from an argument.

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.
