Trait neon::borrow::BorrowMut

pub trait BorrowMut: Borrow {
    fn try_borrow_mut<'a>(
        self, 
        lock: &'a Lock<'a>
    ) -> Result<RefMut<'a, Self::Target>, LoanError>;

    fn borrow_mut<'a>(self, lock: &'a Lock<'a>) -> RefMut<'a, Self::Target> { ... }
}

A trait for JS values whose internal contents can be borrowed mutably by Rust while the JS engine is locked.

Required methods

fn try_borrow_mut<'a>(
    self,
    lock: &'a Lock<'a>
) -> Result<RefMut<'a, Self::Target>, LoanError>

Borrow the contents of this value mutably.

If there is already an outstanding loan for this value, this method panics.

Provided methods

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.
