Struct ScreenshotHandle 

pub struct ScreenshotHandle {
    pub request: Rc<Cell<bool>>,
    pub image: Rc<RefCell<Option<(Vec<u8>, u32, u32)>>>,
}

Shared capture state. Clone freely; all inner fields are Rc<...>.

Fields

request: Rc<Cell<bool>>

Set to true to request a capture on the next rendered frame. The platform harness reads this cell after painting, captures the framebuffer into image, and clears the flag.

image: Rc<RefCell<Option<(Vec<u8>, u32, u32)>>>

Most recent captured image — top-down RGBA8, plus (width, height). None until the first capture completes.

Implementations

impl ScreenshotHandle

pub fn new() -> Self

pub fn take(&self)

Convenience: request a capture. Equivalent to self.request.set(true).

pub fn pending(&self) -> bool

true while the latest request has not yet been fulfilled.

pub fn has_image(&self) -> bool

Access the most recent capture without consuming it.
