Expand description
A trait for JS values whose internal contents can be borrowed mutably by Rust while the JS engine is locked.
Required methods
Provided methods
fn borrow_mut<'a>(self, lock: &'a Lock<'a>) -> RefMut<'a, Self::Target>
fn borrow_mut<'a>(self, lock: &'a Lock<'a>) -> RefMut<'a, Self::Target>
Borrow the contents of this value mutably.
If there is already an outstanding loan for this value, this method panics.
