}

Filesystem-free generation settings. Defaults match the file API’s GenerateWebfontsOptions. Templates are text (Some("") renders empty), not paths. No output is written. Deserializes camelCase fields, rejecting unknown fields and defaulting omitted settings.

Fields

cache: Option<Vec<u8>>

Enable the persistent cache with bytes from an earlier result’s cache_bytes, or an empty vector to start cold. Unchanged icons skip parsing and processing, and unchanged formats are reused. Output is byte-identical to an uncached run. Bytes from another engine version or other settings are ignored. Not deserialized: pass binary data directly.

fallback_ts: Option<i64>

TTF head timestamp used when formatOptions.ttf.ts is unset, for environments without a system clock (WebAssembly). Unlike ts it isn’t part of cache keys, so cached fonts keep the timestamp of the run that created them. Not deserialized.

sources: Vec<SvgSource>

Ordered sources for ordinary generation; empty when variants is supplied.

variants: Option<Vec<SourceFontVariant>>

Ordered variant designs, using the same font encoders as file generation.

css_template: Option<String>

Optional CSS Handlebars source; compiled on first CSS render.

html_template: Option<String>

Optional HTML Handlebars source; compiled on first HTML render.

color_glyphs: Option<ColorGlyphSelection>

Color glyph selection; supports TTF, WOFF and WOFF2.

color_slots: Option<HashMap<String, String>>

Named #RRGGBB palette slots, indexed in ASCII name order; requires active color glyphs.

ascent: Option<f64>

Font ascent.

center_horizontally: Option<bool>

Center glyphs horizontally.

center_vertically: Option<bool>

Center glyphs vertically.

css: Option<bool>

Include CSS in collected outputs (default true).

codepoints: Option<HashMap<String, u32>>

Explicit glyph name to Unicode assignments.

css_fonts_url: Option<String>

URL prefix; absent means relative font filenames in both CSS and HTML.

descent: Option<f64>

Font descent.

fixed_width: Option<bool>

Use a common advance width.

format_options: Option<FormatOptions>

Format-specific encoding settings.

html: Option<bool>

Include HTML in collected outputs (default false).

ts: Option<bool>

Include the fixed TypeScript source module in collected outputs. Defaults to false.

incremental: Option<bool>

Retain geometry and encoder caches for subsequent source updates.

font_height: Option<f64>

Output font height.

font_name: Option<String>

Logical font name (default iconfont).

font_style: Option<String>

Font style.

font_weight: Option<String>

Ordinary font weight; incompatible with variants.

ligature: Option<bool>

Enable name ligatures (default true).

missing_glyphs: Option<MissingGlyphOptions>

Variant missing-glyph policy.

normalize: Option<bool>

Normalize glyph dimensions (default true).

order: Option<Vec<FontType>>

CSS font format preference order.

optimize_output: Option<bool>

Optimize SVG output paths.

preserve_aspect_ratio: Option<bool>

Preserve source aspect ratios.

round: Option<f64>

Coordinate rounding precision.

start_codepoint: Option<u32>

First automatic codepoint (default U+F101).

template_options: Option<Map<String, Value>>

Additional template context values.

threads: Option<NonZeroUsize>

How many threads do glyph work at once (never more than CPU cores), including later source updates. WOFF2’s Brotli worker isn’t counted. Unset uses Rayon’s global pool (RAYON_NUM_THREADS applies). Output is identical for every value. Not deserialized.

types: Option<Vec<FontType>>

Requested formats; ordinary defaults EOT/WOFF/WOFF2, variants WOFF/WOFF2.

variant_class_prefix: Option<String>

Variant CSS modifier prefix (default icon--).
