Implementations

impl<'a> BuiltDisplayListIter<'a>

pub fn new(data: &'a [u8], cache: Option<&'a DisplayItemCache>) -> Self

pub fn sub_iter(&self) -> Self

pub fn current_item(&self) -> &DisplayItem

fn cached_item_range_or<T>(&self, data: ItemRange<'a, T>) -> ItemRange<'a, T>

pub fn glyphs(&self) -> ItemRange<'_, GlyphInstance>

pub fn gradient_stops(&self) -> ItemRange<'_, GradientStop>

fn advance_pending_items(&mut self) -> bool

pub fn next<'b>(&'b mut self) -> Option<DisplayItemRef<'a, 'b>>

pub fn next_raw<'b>(&'b mut self) -> Option<DisplayItemRef<'a, 'b>>

Gets the next display item, even if it’s a dummy. Also doesn’t handle peeking and may leave irrelevant ranges live (so a Clip may have GradientStops if for some reason you ask).

pub fn as_ref<'b>(&'b self) -> DisplayItemRef<'a, 'b>

pub fn skip_current_stacking_context(&mut self)

pub fn current_stacking_context_empty(&mut self) -> bool

pub fn peek<'b>(&'b mut self) -> Option<DisplayItemRef<'a, 'b>>

pub fn debug_stats(&mut self) -> Vec<(&'static str, ItemStats)>

Get the debug stats for what this iterator has deserialized. Should always be empty in release builds.

pub fn merge_debug_stats_from(&mut self, other: &mut Self)

Adds the debug stats from another to our own, assuming we are a sub-iter of the other (so we can ignore where they were in the traversal).

fn log_item_stats(&mut self)
