Struct LendingCell 

pub struct LendingCell<T> { /* private fields */ }

A container that allows borrowing without lifetimes.

let mut lender = LendingCell::new("borrowed");
let borrowed = lender.to_borrowed();
assert!(lender.try_get().is_none()); // `lender` is empty because it was borrowed
assert_eq!(*borrowed, "borrowed"); // it's certain that `borrowed` is valid while in scope
drop(borrowed); // dropping `borrowed` returns its value to `lender`
assert!(lender.try_get().is_some());

Implementations

impl<T> LendingCell<T>

pub fn new(thing: T) -> Self

Creates a new LendingCell with the given value

pub fn try_get(&self) -> Option<&T>

Get a reference to the contained value if it wasn’t borrowed with LendingCell::to_borrowed

pub fn get(&self) -> &T

Get a reference to the contained value if it wasn’t borrowed with LendingCell::to_borrowed, otherwise panic

pub fn try_get_mut(&mut self) -> Option<&mut T>

Get a mutable reference the contained value if it wasn’t borrowed with LendingCell::to_borrowed

pub fn get_mut(&mut self) -> &mut T

Get a mutable reference the contained value if it wasn’t borrowed with LendingCell::to_borrowed, otherwise panic

pub fn to_borrowed(&mut self) -> BorrowedCell<T>

Take the contained value and returned it in an owned object if it isn’t already borrowed, otherwise panic.

pub fn try_to_borrowed(&mut self) -> Option<BorrowedCell<T>>

Take the contained value and returned it in an owned object if it isn’t already borrowed.

pub fn try_into_inner(self) -> Result<T, Self>

Destroy the container and return the contained object if it isn’t being borrowed already. If it fails, return myself LendingCell
