Struct LayoutPruneStats 

pub struct LayoutPruneStats {
    pub subtrees: u64,
    pub nodes: u64,
}

Counters for the scroll-layout prune optimization, which skips recursing into scroll-container children that lie far outside the visible range. Recorded during each layout pass; retrieve the latest pass’s numbers with take_prune_stats.

Fields

subtrees: u64

Off-screen child subtrees whose recursion was skipped.

nodes: u64

Total descendant nodes inside those skipped subtrees.

Trait Implementations

impl Clone for LayoutPruneStats

fn clone(&self) -> LayoutPruneStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LayoutPruneStats

impl Debug for LayoutPruneStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LayoutPruneStats

fn default() -> LayoutPruneStats

Returns the “default value” for a type.

impl Eq for LayoutPruneStats

impl PartialEq for LayoutPruneStats

fn eq(&self, other: &LayoutPruneStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
