Struct VTableView

pub struct VTableView<T>(/* private fields */)
where
    T: ?Sized;

A typed view of a ValueVTable.

Implementations

impl<'a, T> VTableView<&'a mut T>

where T: Facet<'a> + ?Sized,

pub fn of_deref() -> VTableView<&'a mut T>

Fetches the vtable for the type.

impl<'a, T> VTableView<&'a T>

where T: Facet<'a> + ?Sized,

pub fn of_deref() -> VTableView<&'a T>

Fetches the vtable for the type.

impl<'a, T> VTableView<T>

where T: Facet<'a> + ?Sized,

pub fn of() -> VTableView<T>

Fetches the vtable for the type.

pub fn type_name( &self, ) -> fn(&mut Formatter<'_>, TypeNameOpts) -> Result<(), Error>

cf. TypeNameFn

pub fn invariants(&self) -> Option<fn(&T) -> bool>

cf. InvariantsFn

pub fn display(&self) -> Option<fn(&T, &mut Formatter<'_>) -> Result<(), Error>>

cf. DisplayFn

pub fn debug(&self) -> Option<fn(&T, &mut Formatter<'_>) -> Result<(), Error>>

cf. DebugFn

pub fn partial_eq(&self) -> Option<fn(&T, &T) -> bool>

cf. PartialEqFn for equality comparison

pub fn partial_ord(&self) -> Option<fn(&T, &T) -> Option<Ordering>>

cf. PartialOrdFn for partial ordering comparison

pub fn ord(&self) -> Option<fn(&T, &T) -> Ordering>

cf. CmpFn for total ordering

pub fn hash( &self, ) -> Option<for<'mem> fn(&'mem T, PtrMut<'mem>, for<'mem> unsafe fn(PtrMut<'mem>, &[u8]))>

cf. HashFn

pub fn try_borrow_inner( &self, ) -> Option<for<'src> fn(&'src T) -> Result<&'src T, TryBorrowInnerError>>

cf. TryBorrowInnerFn

This is used by transparent types to efficiently access the inner value without copying.

impl<'a, T> VTableView<T>

where T: Facet<'a>,

pub fn default_in_place( &self, ) -> Option<for<'mem> fn(TypedPtrUninit<'mem, T>) -> &'mem mut T>

cf. DefaultInPlaceFn

pub fn clone_into( &self, ) -> Option<for<'src, 'dst> fn(&'src T, TypedPtrUninit<'dst, T>) -> &'dst mut T>

cf. CloneIntoFn

pub fn parse( &self, ) -> Option<for<'mem> fn(&str, TypedPtrUninit<'mem, T>) -> Result<&'mem mut T, ParseError>>

cf. ParseFn

pub fn try_from( &self, ) -> Option<for<'src, 'mem, 'shape> fn(&'src T, &'shape Shape<'shape>, TypedPtrUninit<'mem, T>) -> Result<&'mem mut T, TryFromError<'shape>>>

cf. TryFromFn

This also acts as a “TryFromInner” — you can use it to go:

• String => Utf8PathBuf
• String => Uuid
• T => Option<T>
• T => Arc<T>
• T => NonZero<T>
• etc.

pub fn try_into_inner( &self, ) -> Option<for<'src, 'dst> fn(&'src T, TypedPtrUninit<'dst, T>) -> Result<&'dst mut T, TryIntoInnerError>>

cf. TryIntoInnerFn

This is used by transparent types to convert the wrapper type into its inner value. Primarily used during serialization.

Trait Implementations

impl<T> Debug for VTableView<T>

where T: Debug + ?Sized,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Hash for VTableView<T>

where T: Hash + ?Sized,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq for VTableView<T>

where T: PartialEq + ?Sized,

fn eq(&self, other: &VTableView<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Eq for VTableView<T>

where T: Eq + ?Sized,

impl<T> StructuralPartialEq for VTableView<T>

where T: ?Sized,
