Module intrinsic 

Intrinsic measurers for components whose box size depends on content.

Uses the same Skia metrics that the painter uses, so the box reserved by taffy matches the pixels actually drawn — measure-vs-paint mismatches would otherwise cause text to wrap onto an extra line at paint time and overflow into the next sibling.

Structs

BadgeIntrinsic

Intrinsic measurer for Badge — measures the label text plus icon, gap, and the size-derived horizontal/vertical padding.

CaptionIntrinsic

Intrinsic measurer for Caption. Concatenates the words with single spaces and measures the result like a regular text run.

CodeblockIntrinsic

Intrinsic measurer for Codeblock.

CounterIntrinsic

Intrinsic measurer for Counter — reserves space for the largest absolute value the counter will display so layout never reflows during animation.

GradientTextIntrinsic

Cosmic-text–backed intrinsic measurer for GradientText — same content model as Text (a single string + style); the gradient is purely a paint-time concern and doesn’t change box dimensions.

KbdIntrinsic

Intrinsic measurer for Kbd — measures the key text plus the legacy keyboard-cap padding (h ≈ font_size × 0.7, v ≈ font_size × 0.4) and enforces a min-width of font_size × 1.8.

NumberWheelIntrinsic

Intrinsic measurer for crate::number_wheel::NumberWheel.

RichTextIntrinsic

Intrinsic measurer for RichText.

TableIntrinsic

Intrinsic measurer for Table.

TerminalIntrinsic

Intrinsic measurer for Terminal.

TextIntrinsic

Skia-backed intrinsic measurer for Text (audit #10: despite the name this module’s doc header suggests, this uses skia_safe::Font:: measure_str via engine::renderer::text’s fallback-aware helpers — the same primitives Text::paint draws with — not engine::text::cosmic, which has no callers on the real render path at all; see that module’s doc comment).

Functions

font_size_ctx

LengthContext for resolving font-size (and, through CssStyle::typography_px_ctx, letter-spacing/line-height derived from it) against a real, per-frame viewport. Use from Painter:: paint_content and friends, which have a real PaintCtx (video_width/ video_height) on hand.

measure_time_font_size_ctx

Same as font_size_ctx, for the Intrinsic measurers in this module: they run at box_builder/geometry construction time, before layout, so there is no real per-frame viewport to hand (see the pre-existing note on TextIntrinsic::from_parts, which has the same limitation for letter-spacing/line-height). Falls back to the engine-wide default 1920×1080 (same as LengthContext::default()) so rem — which does not depend on the viewport at all — still resolves exactly, and vw/vh get a reasonable non-zero approximation instead of silently dropping to 0. This can diverge from what Painter::paint_content resolves via font_size_ctx for vw/vh specifically, on videos that aren’t 1920×1080 — closing that fully needs the real VideoConfig threaded through box_builder.rs/geometry.rs, both outside this workstream.

resolve_text_autofit

text-autofit’s shared shrink resolution — the single computation TextIntrinsic::measure and Text/GradientText’s painters all call with identical inputs, so the resolved size can never disagree between the box taffy reserves and the pixels actually painted into it (see CssStyle::text_autofit’s doc comment — this exact class of bug is what this workstream exists to close, not reopen).
