Struct RenderImageCallbackInfo 

pub struct RenderImageCallbackInfo { /* private fields */ }

Information passed to image rendering callbacks

Implementations

impl RenderImageCallbackInfo

pub const fn new<'a>( callback_node_id: DomNodeId, bounds: HidpiAdjustedBounds, gl_context: &'a OptionGlContextPtr, image_cache: &'a ImageCache, system_fonts: &'a FcFontCache, ) -> Self

pub fn get_ctx(&self) -> OptionRefAny

Get the callable for FFI language bindings (Python, etc.)

pub const unsafe fn set_callable_ptr(&mut self, ptr: *const OptionRefAny)

Set the callable pointer (called before invoking callback)

Safety

ptr must either be null or point to an OptionRefAny that stays valid for as long as this CallbackInfo may read it (i.e. until the pointer is replaced or the callback returns). The pointee is read by get_ctx; a dangling or misaligned ptr is undefined behavior.

pub const fn get_callback_node_id(&self) -> DomNodeId

pub const fn get_bounds(&self) -> HidpiAdjustedBounds

pub fn get_gl_context(&self) -> OptionGlContextPtr
