Enum ValueVTable

#[repr(C)]
pub enum ValueVTable {
    Sized(ValueVTableSized),
    Unsized(ValueVTableUnsized),
}

A vtable representing the operations that can be performed on a type, either for sized or unsized types.

This enum encapsulates the specific vtables for sized (ValueVTableSized) and unsized (ValueVTableUnsized) shapes, allowing generic type-agnostic dynamic dispatch for core capabilities (clone, drop, compare, hash, etc).

Variants

Sized(ValueVTableSized)

VTable for operations on sized types.

Unsized(ValueVTableUnsized)

VTable for operations on unsized types.

Implementations

impl ValueVTable

pub const fn sized(&self) -> Option<&ValueVTableSized>

Returns a reference to the ValueVTableSized if this vtable is for a sized type.

Returns

• Some(&ValueVTableSized) if the type is sized.
• None if the type is unsized.

pub const fn sized_mut(&mut self) -> Option<&mut ValueVTableSized>

Returns a mutable reference to the ValueVTableSized if this vtable is for a sized type.

Returns

• Some(&mut ValueVTableSized) if the type is sized.
• None if the type is unsized.

pub const fn unsized(&self) -> Option<&ValueVTableUnsized>

Returns a reference to the ValueVTableUnsized if this vtable is for an unsized type.

Returns

• Some(&ValueVTableUnsized) if the type is unsized.
• None if the type is sized.

pub fn has_display(&self) -> bool

Returns true if the type implements the Display trait and the display function is available in the vtable.

pub fn has_debug(&self) -> bool

Returns true if the type implements the Debug trait and the debug function is available in the vtable.

pub fn has_partial_eq(&self) -> bool

Returns true if the type implements the PartialEq trait and the partial_eq function is available in the vtable.

pub fn has_partial_ord(&self) -> bool

Returns true if the type implements the PartialOrd trait and the partial_ord function is available in the vtable.

pub fn has_ord(&self) -> bool

Returns true if the type implements the Ord trait and the ord function is available in the vtable.

pub fn has_hash(&self) -> bool

Returns true if the type implements the Hash trait and the hash function is available in the vtable.

pub fn has_default_in_place(&self) -> bool

Returns true if the type supports default-in-place construction via the vtable.

pub fn has_clone_into(&self) -> bool

Returns true if the type supports in-place cloning via the vtable.

pub fn has_parse(&self) -> bool

Returns true if the type supports parsing from a string via the vtable.

Trait Implementations

impl Clone for ValueVTable

fn clone(&self) -> ValueVTable

Returns a duplicate 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.
