Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

type_name: TypeNameFn

cf. TypeNameFn

marker_traits: fn() -> MarkerTraits

Marker traits implemented by the type

drop_in_place: fn() -> Option<DropInPlaceFnWide>

cf. DropInPlaceFn — if None, drops without side-effects

invariants: fn() -> Option<InvariantsFnWide>

cf. InvariantsFn

display: fn() -> Option<DisplayFnWide>

cf. DisplayFn

debug: fn() -> Option<DebugFnWide>

cf. DebugFn

partial_eq: fn() -> Option<PartialEqFnWide>

cf. PartialEqFn for equality comparison

partial_ord: fn() -> Option<PartialOrdFnWide>

cf. PartialOrdFn for partial ordering comparison

ord: fn() -> Option<CmpFnWide>

cf. CmpFn for total ordering

hash: fn() -> Option<HashFnWide>

cf. HashFn

try_borrow_inner: fn() -> Option<TryBorrowInnerFnWide>

cf. TryBorrowInnerFn

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

Trait Implementations

impl Clone for ValueVTableUnsized

fn clone(&self) -> ValueVTableUnsized

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueVTableUnsized

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

Formats the value using the given formatter.

impl Hash for ValueVTableUnsized

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

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 PartialEq for ValueVTableUnsized

fn eq(&self, other: &ValueVTableUnsized) -> 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.
