Struct Reborrow

pub struct Reborrow<'b, S: ?Sized, Tk: Token + ?Sized> { /* private fields */ }

Stateful wrapper around a borrowed token shared reference.

Implementations

impl<'b, S: ?Sized, Tk: Token + ?Sized> Reborrow<'b, S, Tk>

pub fn reborrow<U: ?Sized>( &mut self, cell: impl FnOnce(&mut S) -> &TokenRefCell<U, Tk>, ) -> Ref<'_, U, Tk>

Uses borrowed token shared reference to reborrow a TokenRefCell.

Panics

See TokenRefCell::borrow.

pub fn try_reborrow<U: ?Sized>( &mut self, cell: impl FnOnce(&mut S) -> &TokenRefCell<U, Tk>, ) -> Result<Ref<'_, U, Tk>, BorrowError>

Uses borrowed token shared reference to reborrow a TokenRefCell.

See TokenRefCell::try_borrow.

pub fn reborrow_opt<U: ?Sized>( &mut self, cell: impl FnOnce(&mut S) -> Option<&TokenRefCell<U, Tk>>, ) -> Option<Ref<'_, U, Tk>>

Uses borrowed token shared reference to optionally reborrow a TokenRefCell.

Panics

See TokenRefCell::borrow.

pub fn try_reborrow_opt<U: ?Sized>( &mut self, cell: impl FnOnce(&mut S) -> Option<&TokenRefCell<U, Tk>>, ) -> Option<Result<Ref<'_, U, Tk>, BorrowError>>

Uses borrowed token shared reference to optionally reborrow a TokenRefCell.

See TokenRefCell::try_borrow.

pub fn token_id(&self) -> Tk::Id

Get the id of the borrowed token.
