Struct Ref 

pub struct Ref<'a, T: ?Sized> { /* private fields */ }

Shared (immutable) borrow guard for account data.

On drop, decrements the borrow count in RuntimeAccount.borrow_state.

Implementations

impl<'a, T: ?Sized> Ref<'a, T>

pub unsafe fn from_raw_parts(value: &'a T, state: *mut u8) -> Self

Create a shared borrow guard from raw parts.

Safety

The caller must ensure:

• The borrow state at state was already incremented
• value is valid for lifetime 'a
• state points to a valid RuntimeAccount.borrow_state

pub fn into_raw_parts(self) -> (&'a T, *mut u8)

Decompose into raw parts without running the destructor.

The caller takes responsibility for eventually releasing the borrow (decrementing *state).

Trait Implementations

impl<T: ?Sized> Deref for Ref<'_, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: ?Sized> Drop for Ref<'_, T>

fn drop(&mut self)

Executes the destructor for this type.
