Enum Ox 

pub enum Ox<'a> {
    Owned(OxMut<'a>),
    Borrowed(OxRef<'a>),
}

Type-erased value with ownership tracking — like Cow but for any shape.

Variants

Owned(OxMut<'a>)

We own this value and must drop it.

Borrowed(OxRef<'a>)

We’re borrowing this value; someone else drops it.

Implementations

impl Ox<'static>

pub fn from_boxed<T: Facet<'static>>(boxed: Box<T>) -> Self

Take ownership of a boxed value.

pub fn new<T: Facet<'static>>(value: T) -> Self

Take ownership of a value by boxing it.

impl<'a> Ox<'a>

pub fn as_ref(&self) -> OxRef<'_>

Get an immutable view of the value.

pub fn as_mut(&mut self) -> Option<OxMut<'_>>

Get a mutable view of the value (only if owned).

pub fn ptr_const(&self) -> PtrConst

For read-only vtable operations.

pub fn ptr_mut(&mut self) -> Option<PtrMut>

For mutating vtable operations (only if owned).

pub fn shape(&self) -> &'static Shape

Get the shape.

pub unsafe fn get_as<T: 'static>( &self, expected_shape: &'static Shape, ) -> Option<&T>

Get a typed reference if the shape matches.

Safety

The caller must ensure that T is the correct type for expected_shape.

Trait Implementations

impl Debug for Ox<'_>

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

Formats the value using the given formatter.

impl Display for Ox<'_>

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

Formats the value using the given formatter.

impl Drop for Ox<'_>

fn drop(&mut self)

Executes the destructor for this type.

impl Hash for Ox<'_>

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 Ox<'_>

fn eq(&self, other: &Self) -> 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 PartialOrd for Ox<'_>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
