Struct RefAny 

#[repr(C)]
pub struct RefAny {
    pub _internal_ptr: *const c_void,
    pub sharing_info: RefCount,
    pub instance_id: u64,
    pub run_destructor: bool,
}

Fields

_internal_ptr: *const c_void

void* to a boxed struct or enum of type “T”. RefCount stores the RTTI for this opaque type (can be downcasted by the user)

sharing_info: RefCount

All the metadata information is set on the refcount, so that the metadata has to only be created once per object, not once per copy

instance_id: u64

Instance of this copy (root = 0th copy).

Necessary to distinguish between the original copy and all other clones

run_destructor: bool

Implementations

impl RefAny

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

Creates a new, type-erased pointer by casting the T value into a Vec<u8> and saving the length + type ID

pub fn new_c( ptr: *const c_void, len: usize, type_id: u64, type_name: AzString, custom_destructor: extern "C" fn(&mut c_void), ) -> Self

C-ABI compatible function to create a RefAny across the C boundary

pub fn has_no_copies(&self) -> bool

Returns whether this RefAny is the only instance

pub fn downcast_ref<'a, U: 'static>(&'a mut self) -> Option<Ref<'a, U>>

Downcasts the type-erased pointer to a type &U, returns None if the types don’t match

pub fn downcast_mut<'a, U: 'static>(&'a mut self) -> Option<RefMut<'a, U>>

Downcasts the type-erased pointer to a type &mut U, returns None if the types don’t match

pub fn is_type(&self, type_id: u64) -> bool

Checks whether the typeids match

pub fn get_type_id(&self) -> u64

pub fn get_type_name(&self) -> AzString

Trait Implementations

impl Clone for RefAny

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefAny

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

Formats the value using the given formatter.

impl Drop for RefAny

fn drop(&mut self)

Executes the destructor for this type.

impl Hash for RefAny

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 Ord for RefAny

fn cmp(&self, other: &RefAny) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RefAny

fn eq(&self, other: &RefAny) -> 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 RefAny

fn partial_cmp(&self, other: &RefAny) -> 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.
