Struct Ref

pub struct Ref<'a, Target: PartialRefTarget + ?Sized> { /* private fields */ }

An empty partial reference borrowing no parts.

Partial references with a non-empty set of borrowed parts are built by nesting this type within the Mut and Const types.

Trait Implementations

impl<'a, Target: PartialRefTarget> Clone for Ref<'a, Target>

An empty reference contains no mutable parts and thus is safe to clone.

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, Target: PartialRefTarget + ?Sized> HasTarget for Ref<'a, Target>

type Target = Target

The referenced type.

impl<'a, 'b: 'a, Target: PartialRefTarget + ?Sized> PartialRef<'a> for Ref<'b, Target>

An empty reference to a valid target is a valid reference.

unsafe fn from_raw( ptr: *mut <Self::Target as PartialRefTarget>::RawTarget, ) -> Self

Create a partial reference from a raw pointer.

fn get_raw(&self) -> *mut <Self::Target as PartialRefTarget>::RawTarget

Access to the underlying raw pointer.

fn borrow<BorrowedRef, SubsetIndex>(&'a mut self) -> BorrowedRef

where BorrowedRef: PartialRef<'a, Target = Self::Target>, Self: HasSubset<'a, BorrowedRef, SubsetIndex>,

Partially re-borrows a partial reference.

fn part<FieldPartSpec, FieldPart, PartIndex, FieldType>( &'a self, _part: FieldPartSpec, ) -> &'a FieldType

where FieldType: ?Sized, FieldPart: Part<PartType = Field<FieldType>>, FieldPartSpec: PartSpec<FieldPart>, Self: PluckConst<'a, FieldPart, PartIndex>, Self::Target: HasPart<FieldPart> + 'a,

Access a part of the referenced value.

fn part_mut<FieldPartSpec, FieldPart, PartIndex, FieldType>( &'a mut self, _part: FieldPartSpec, ) -> &'a mut FieldType

where FieldType: ?Sized, FieldPart: Part<PartType = Field<FieldType>>, FieldPartSpec: PartSpec<FieldPart>, Self: PluckMut<'a, FieldPart, PartIndex>, Self::Target: HasPart<FieldPart> + 'a,

Mutable access to a part of the referenced value.

fn split_borrow<BorrowedRef, SubsetIndex>( &'a mut self, ) -> (BorrowedRef, Self::Remainder)

where BorrowedRef: PartialRef<'a, Target = Self::Target>, Self: HasSubset<'a, BorrowedRef, SubsetIndex>,

Partially re-borrows a partial reference, splitting off the remaining parts.

fn split_part<FieldPartSpec, FieldPart, PartIndex, FieldType>( &'a mut self, _part: FieldPartSpec, ) -> (&'a FieldType, Self::Remainder)

where FieldType: ?Sized, FieldPart: Part<PartType = Field<FieldType>>, FieldPartSpec: PartSpec<FieldPart>, Self: PluckConst<'a, FieldPart, PartIndex>, Self::Target: HasPart<FieldPart> + 'a,

Access a part of the referenced value, splitting off the remaining parts.

fn split_part_mut<FieldPartSpec, FieldPart, PartIndex, FieldType>( &'a mut self, _part: FieldPartSpec, ) -> (&'a mut FieldType, Self::Remainder)

where FieldType: ?Sized, FieldPart: Part<PartType = Field<FieldType>>, FieldPartSpec: PartSpec<FieldPart>, Self: PluckMut<'a, FieldPart, PartIndex>, Self::Target: HasPart<FieldPart> + 'a,

Mutable access to a part of the referenced value, splitting off the remaining parts.

impl<'a, Target: PartialRefTarget> Copy for Ref<'a, Target>

An empty reference contains no mutable parts and thus is safe to clone.
