Struct FontVariations 

pub struct FontVariations(/* private fields */);

Precise author coordinates, independent of any interactive preview policy.

Settings are sorted by tag; the last duplicate wins. Values are finite signed f32 coordinates with negative zero normalized. No quantization is performed. Explicit settings override implicit weight/style coordinates after face selection. Unsupported axes are ignored per face; supported values are clamped per face.

Implementations

impl FontVariations

pub fn new(settings: impl IntoIterator<Item = (FontTag, f32)>) -> Result<Self>

Validates and canonicalizes settings. Invalid values, even in overwritten entries, are rejected. Empty settings preserve backend defaults.

pub fn settings(&self) -> &[(FontTag, f32)]

Returns canonical settings in tag order, in the font’s design units.

Trait Implementations

impl Clone for FontVariations

fn clone(&self) -> Self

Formats the value using the given formatter.

impl Default for FontVariations

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontVariations

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.
