Struct LateInstanceDyn 

pub struct LateInstanceDyn<S: LateStruct> { /* private fields */ }

A view around a LateInstance which exposes a RefCell-like API for dynamically borrowing multiple fields mutably at the same time.

Implementations

impl<S: LateStruct> LateInstanceDyn<S>

pub fn non_dynamic(&mut self) -> &mut LateInstance<S>

Obtains a reference to the underlying LateInstance.

pub fn init_token(&self) -> LateLayoutInitToken

Forwards to LateInstance::init_token.

pub fn fields(&self) -> &'static [&'static LateFieldDescriptor<S>]

Forwards to LateInstance::fields.

pub fn get_ptr<F: LateField<S>>(&self) -> NonNull<F::Value>

Forwards to LateInstance::get_ptr.

pub fn get_erased_ptr( &self, field: &LateFieldDescriptor<S>, ) -> NonNull<S::EraseTo>

Forwards to LateInstance::get_erased_ptr.

pub fn get_mut<F: LateField<S>>(&mut self) -> &mut F::Value

Forwards to LateInstance::get_mut.

pub fn borrow<F: LateField<S>>(&self) -> Ref<'_, F::Value>

Borrow the field identified by the supplied LateField marker type immutably, panicking if the borrow failed.

The smart-pointers returned by this method are compatible with those returned by RefCell.

pub fn borrow_mut<F: LateField<S>>(&self) -> RefMut<'_, F::Value>

Borrow the field identified by the supplied LateField marker type mutably, panicking if the borrow failed.

The smart-pointers returned by this method are compatible with those returned by RefCell.

pub fn try_borrow<F: LateField<S>>( &self, ) -> Result<Ref<'_, F::Value>, BorrowError>

Borrow the field identified by the supplied LateField marker type immutably or return a cell::BorrowError if the borrow failed.

The smart-pointers and errors returned by this method are compatible with those returned by RefCell.

pub fn try_borrow_mut<F: LateField<S>>( &self, ) -> Result<RefMut<'_, F::Value>, BorrowMutError>

Borrow the field identified by the supplied LateField marker type mutably or return a cell::BorrowError if the borrow failed.

The smart-pointers and errors returned by this method are compatible with those returned by RefCell.

pub fn borrow_erased<'a>( &'a self, field: &LateFieldDescriptor<S>, ) -> Ref<'a, S::EraseTo>

Borrow the field identified by the supplied LateFieldDescriptor immutably, panicking if the borrow failed.

The smart-pointers returned by this method are compatible with those returned by RefCell.

pub fn borrow_erased_mut<'a>( &'a self, field: &LateFieldDescriptor<S>, ) -> RefMut<'a, S::EraseTo>

Borrow the field identified by the supplied LateFieldDescriptor mutably, panicking if the borrow failed.

The smart-pointers returned by this method are compatible with those returned by RefCell.

pub fn try_borrow_erased<'a>( &'a self, field: &LateFieldDescriptor<S>, ) -> Result<Ref<'a, S::EraseTo>, BorrowError>

Borrow the field identified by the supplied LateFieldDescriptor immutably or return a cell::BorrowError if the borrow failed.

The smart-pointers and errors returned by this method are compatible with those returned by RefCell.

pub fn try_borrow_erased_mut<'a>( &'a self, field: &LateFieldDescriptor<S>, ) -> Result<RefMut<'a, S::EraseTo>, BorrowMutError>

Borrow the field identified by the supplied LateFieldDescriptor mutably or return a cell::BorrowMutError if the borrow failed.

The smart-pointers and errors returned by this method are compatible with those returned by RefCell.
