Struct BSExtraData

#[repr(C)]
pub struct BSExtraData {
    pub vtbl: *const BSExtraDataVtbl,
    pub next: *mut BSExtraData,
    /* private fields */
}

Represents the base structure for extra data nodes in a singly linked list.

Fields

vtbl: *const BSExtraDataVtbl

Pointer to the virtual function table (vtable).

next: *mut BSExtraData

Pointer to the next BSExtraData node.

This is a raw pointer to ensure FFI compatibility. Option<NonNull<T>> would be safer, but raw pointers are required for interoperability.

Note

This is assumed to be a heap-derived unique pointer created from Box::into_raw, etc.

If this process is broken, UB happens.

Implementations

impl BSExtraData

pub const RTTI: VariantID = RTTI_BSExtraData

Address & offset of RTTI for BSExtraData.

pub const VTABLE: [VariantID; 1] = VTABLE_BSExtraData

Address & offset of Virtual function table.

pub const EXTRA_DATA_TYPE: ExtraDataType = ExtraDataType::None

Default extra data type (None).

pub const fn new() -> Self

Creates a new instance of BSExtraData with default values.

pub fn get_type(&self) -> ExtraDataType

Get the extra data type by invoking the GetType virtual function.

pub fn is_not_equal(&self, rhs: &Self) -> bool

Compares two BSExtraData instances for inequality.

pub fn create<T: CxxVirtClass>() -> Option<NonNull<T>>

Creates a new instance of T that implements CxxVirtClass.

Returns an Option<NonNull<T>> containing a pointer to the allocated instance, or None on failure.

pub fn create_with( size: usize, vtbl: NonNull<c_void>, ) -> Option<NonNull<c_void>>

Allocates and initializes a new BSExtraData instance with a given size and vtable.

Returns

The pointer to the allocated instance.

Trait Implementations

impl CxxVirtClass for BSExtraData

fn rtti() -> &'static VariantID

Gets the runtime information address ID reference.

fn vtable() -> &'static [VariantID]

Gets the virtual function table address reference.

impl Debug for BSExtraData

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

Formats the value using the given formatter.

impl Default for BSExtraData

fn default() -> Self

Returns the “default value” for a type.

impl DerivedBSExtraData for BSExtraData

fn get_extra_data(&self) -> &BSExtraData

Type used for downcast-ing availability and linked list search.

fn get_extra_data_type() -> ExtraDataType

Function for testing whether BSExtraData is really inherited. It will not be called in practice.

impl PartialEq for BSExtraData

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