Required Methods

fn new() -> Self

Initial value for self

fn try_borrow(&self) -> Result<(), PyBorrowError>

Increments immutable borrow count, if possible

fn try_borrow_unguarded(&self) -> Result<(), PyBorrowError>

fn release_borrow(&self)

Decrements immutable borrow count

fn try_borrow_mut(&self) -> Result<(), PyBorrowMutError>

Increments mutable borrow count, if possible

fn release_borrow_mut(&self)

Decremements mutable borrow count
