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

display: Option<DisplayFn>

cf. DisplayFn

debug: Option<DebugFn>

cf. DebugFn

default_in_place: Option<DefaultInPlaceFn>

cf. DefaultInPlaceFn

clone_into: Option<CloneIntoFn>

cf. [CloneInPlaceFn]

marker_traits: MarkerTraits

Marker traits implemented by the type

eq: Option<PartialEqFn>

cf. PartialEqFn for equality comparison

partial_ord: Option<PartialOrdFn>

cf. PartialOrdFn for partial ordering comparison

ord: Option<CmpFn>

cf. CmpFn for total ordering

hash: Option<HashFn>

cf. HashFn

drop_in_place: Option<DropInPlaceFn>

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

parse: Option<ParseFn>

Trait Implementations

impl Clone for ValueVTable

fn clone(&self) -> ValueVTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueVTable

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

Formats the value using the given formatter.

impl Hash for ValueVTable

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 ValueVTable

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