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 const fn of() -> VTableView<T>

Fetches the vtable for the type.

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

cf. TypeNameFn

pub fn invariants(&self) -> Option<fn(TypedPtrConst<'_, T>) -> bool>

cf. InvariantsFn

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

cf. DisplayFn

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

cf. DebugFn

pub fn partial_eq( &self, ) -> Option<fn(TypedPtrConst<'_, T>, TypedPtrConst<'_, T>) -> bool>

cf. PartialEqFn for equality comparison

pub fn partial_ord( &self, ) -> Option<fn(TypedPtrConst<'_, T>, TypedPtrConst<'_, T>) -> Option<Ordering>>

cf. PartialOrdFn for partial ordering comparison

pub fn ord( &self, ) -> Option<fn(TypedPtrConst<'_, T>, TypedPtrConst<'_, T>) -> Ordering>

cf. CmpFn for total ordering

pub fn hash( &self, ) -> Option<for<'mem> fn(TypedPtrConst<'mem, T>, &mut dyn Hasher)>

cf. HashFn

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

cf. DefaultInPlaceFn

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

cf. CloneIntoFn

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

cf. ParseFn

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

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(TypedPtrConst<'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.
