Struct BackdropRecording 

pub struct BackdropRecording { /* private fields */ }

Records the surfaces drawn in the blurred material on this thread until Self::finish. Nests: an inner recording hides the outer one and restores it when it ends.

Implementations

impl BackdropRecording

pub fn begin() -> BackdropRecording

pub fn continuing(surfaces: Vec<RecordedBackdrop>) -> BackdropRecording

Resume a recording whose Self::finish returned surfaces, for a frame painted in more than one pass (a main pass, then a top layer drawn later into the same scene). New surfaces take the region slots after surfaces, so the frame’s placeholders stay distinct and MAX_BACKDROP_REGIONS counts the whole frame. Name the scenes again with layer_scene.

pub fn finish(self) -> Vec<RecordedBackdrop>

The surfaces drawn since Self::begin, bottom to top. A surface whose nested scene never reached a named one is not among them; its placeholder shows the opaque material.

Trait Implementations

impl Drop for BackdropRecording

fn drop(&mut self)

Executes the destructor for this type.

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.
