Struct OwnedDrawData 

pub struct OwnedDrawData { /* private fields */ }

A container for a heap-allocated deep copy of a DrawData struct.

Notes on thread-safety:

• This type intentionally does NOT implement Send/Sync. Although draw lists are cloned, draw commands can still carry raw texture references and backend-specific assumptions.
• The context-owned texture request list is not copied. Use crate::render::snapshot::FrameSnapshot when you need texture requests or thread-safe rendering data detached from the ImGui context.

The underlying copy is released when this struct is dropped.

Implementations

impl OwnedDrawData

pub fn draw_data(&self) -> Option<&DrawData>

If this struct contains a DrawData object, then this function returns a reference to it.

Otherwise, this struct is empty and so this function returns None.

Trait Implementations

impl Default for OwnedDrawData

fn default() -> Self

The default OwnedDrawData struct is empty.

impl Drop for OwnedDrawData

fn drop(&mut self)

Releases any heap-allocated memory consumed by this OwnedDrawData object

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl From<&DrawData> for OwnedDrawData

fn from(value: &DrawData) -> Self

Construct OwnedDrawData from DrawData by creating a heap-allocated deep copy of the given DrawData

impl From<&mut DrawData> for OwnedDrawData

fn from(value: &mut DrawData) -> Self

Construct OwnedDrawData from mutable draw data by reborrowing it as shared draw data.
