Implementations

impl SoftwareTextFont

pub fn from_bytes( bytes: impl Into<Vec<u8>>, ) -> Result<Self, SoftwareTextFontError>

pub fn from_registered_bytes( family: &FontFamily, weight: FontWeight, style: FontStyle, bytes: impl Into<Vec<u8>>, ) -> Result<Self, SoftwareTextFontError>

Parse bytes as a face an app registered under family, declaring weight and style for it.

The declaration wins over the face’s own OS/2 values, the way a Compose Font(resId, FontWeight.Medium) entry does, and a variable face is instanced on its wght/ital axes so one file can back a whole family. That last part is what makes Android’s sans-serif reachable: the platform ships a single variable Roboto-Regular.ttf and describes every weight of the family as an axis position on it.

pub fn from_registered_bytes_with_variations( family: &FontFamily, weight: FontWeight, style: FontStyle, bytes: impl Into<Vec<u8>>, variations: &[([u8; 4], f32)], ) -> Result<Self, SoftwareTextFontError>

Register a face with explicit OpenType axis coordinates shared by measurement, kerning, and rasterization. Coordinates override the declared weight/style axes; repeated tags use the last value. Unknown, nonfinite, or out-of-range values fail.

pub fn family_names(&self) -> &[String]

pub fn registered_family(&self) -> Option<FontFamilyKey>

The family an app registered this face under, if any.

pub fn weight(&self) -> FontWeight

pub fn style(&self) -> FontStyle

pub fn content_hash(&self) -> u64

Stable hash of the font binary — cache-key component wherever rasterized output depends on which font served the run.
