Struct TextAtlasStats

pub struct TextAtlasStats {
    pub hits: u32,
    pub misses: u32,
    pub rasterized: u32,
    pub resets: u32,
    pub evictions_blocked: u32,
    pub glyphs_skipped: u32,
    pub pages_active: u32,
}

Per-frame atlas cache statistics.

Counters saturate at u32::MAX; pages_active reflects the current atlas, including pages allocated in earlier frames.

Examples

use ailloli_ui_render_wgpu::text::TextAtlasStats;
let stats = TextAtlasStats::default();
assert_eq!((stats.hits, stats.misses, stats.pages_active), (0, 0, 0));

Fields

hits: u32

Cache hits in the current frame.

misses: u32

Cache misses in the current frame.

rasterized: u32

Glyph bitmaps uploaded in the current frame.

resets: u32

Atlas page resets caused by eviction in the current frame.

evictions_blocked: u32

Allocations skipped because every candidate page was frame-pinned.

glyphs_skipped: u32

Glyphs skipped for missing faces, raster failures, or allocation failure.

pages_active: u32

Total allocated atlas pages after the latest operation.

Trait Implementations

impl Clone for TextAtlasStats

fn clone(&self) -> TextAtlasStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextAtlasStats

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

Formats the value using the given formatter.

impl Default for TextAtlasStats

fn default() -> TextAtlasStats

Returns the “default value” for a type.

impl PartialEq for TextAtlasStats

fn eq(&self, other: &TextAtlasStats) -> 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.
