Struct SvgData 

pub struct SvgData {
    pub intrinsic: Vec2,
    pub tree: Tree,
    pub id: u64,
    pub source_bytes: usize,
}

Parsed SVG payload produced once at decode time and shared per-frame via Handle<SvgData> clones.

Fields

intrinsic: Vec2

Native pixel size derived from the SVG viewBox / width / height.

tree: Tree

The parsed document, painted at frame time by the renderer.

id: u64

Identity of this decode, unique for the life of the process. A renderer keys its cached drawing of the SVG on it; see SvgData::next_id.

source_bytes: usize

Raw source-file length in bytes; budgeted by the LRU as a proxy for the parsed tree’s cost, which usvg does not expose, so eviction is not blind to SVG memory pressure.

Implementations

impl SvgData

pub fn next_id() -> u64

A fresh SvgData::id. Never repeats within a process, so a renderer cache keyed on it cannot hand one SVG another’s drawing.

Trait Implementations

impl AssetSize for SvgData

fn bytes(&self) -> usize

Returns the approximate CPU-side byte cost of this asset, consulted by AssetServer::bytes_used and the LRU eviction sweep.
