impl<'js, T> JsCell<'js, T>

where T: JsClass<'js>,

pub fn new(t: T) -> JsCell<'js, T>

pub fn try_borrow<'a>(&'a self) -> Result<Borrow<'a, 'js, T>, BorrowError>

Try to borrow the contained value immutable.

pub fn borrow_mut<'a>(&'a self) -> BorrowMut<'a, 'js, T>

Borrow the contained value mutably.

Panic
