Struct RenderKey 

pub struct RenderKey {
    pub page: Option<u32>,
    pub density: u32,
    pub ext: &'static str,
}

Render-shaping inputs that go into the cache key alongside source bytes. Two calls with the same RenderKey MUST produce byte-equivalent output (modulo metadata variation tools like ImageMagick are known to introduce — see compare_outputs_strict audit in the spawn paths).

Fields

page: Option<u32>

1-based page selector (graphicx convention). None ⇒ default.

density: u32

DPI for raster conversions; 0 for pure vector (SVG) paths.

ext: &'static str

Target format, derived from destination extension (lowercase, no dot). e.g. "png", "svg", "jpg". Empty if missing.
