Struct SoftwareTextFontSet 

pub struct SoftwareTextFontSet { /* private fields */ }

Implementations

impl SoftwareTextFontSet

pub fn empty() -> Self

pub fn from_font(font: SoftwareTextFont) -> Self

pub fn from_faces(fonts: Vec<SoftwareTextFont>) -> Self

Build a set from already-parsed faces, keeping the default-face choice and the registered-family index in one place.

pub fn with_installed_faces(&self) -> Option<Self>

This set with the faces installed through install_font_file after its own, or None while no face was installed since it was built.

Installed faces only join the end, so every face keeps its index and a style resolves to the face it resolved to before; the installed faces cover the characters the set’s own faces lack.

pub fn from_fonts_or_default(fonts: &[&'static [u8]]) -> Self

pub fn default_font(&self) -> Option<&SoftwareTextFont>

pub fn faces(&self) -> &[SoftwareTextFont]

Every face in the set, in registration order.

pub fn has_registered_family(&self, family: &FontFamily) -> bool

Whether any face in the set was registered under family.

pub fn resolve(&self, style: &TextStyle) -> Option<&SoftwareTextFont>

Resolves the family and style, then uses Compose’s directional CSS weight matching: lighter first below 400, heavier first above 500, and weights up to 500 before lighter or heavier alternatives in the 400–500 interval.
