Trait neon::borrow::Borrow

pub trait Borrow: Sized {
    type Target: Pointer;
    fn try_borrow<'a>(
        self, 
        lock: &'a Lock<'a>
    ) -> Result<Ref<'a, Self::Target>, LoanError>;

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

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

Associated Types

type Target: Pointer

The type of the value's internal contents.

Required methods

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

Borrow the contents of this value immutably.

If there is already an outstanding mutable loan for this value, this method fails with a LoanError.

Provided methods

fn borrow<'a>(self, lock: &'a Lock<'a>) -> Ref<'a, Self::Target>

Borrow the contents of this value immutably.

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