Struct FontSource 

pub struct FontSource {
    pub bytes: Vec<u8>,
    pub family: String,
    pub name: String,
    pub style: String,
    pub declared: Option<FaceAttributes>,
}

A font entering the engine: raw bytes and the identity the style tree matched against.

Bytes are opaque here — layout never decodes images or fonts twice; decoding happens once, at registration.

Fields

bytes: Vec<u8>

The full font file (TTF/OTF). Registry-owned; callers hand over a copy.

family: String

Family name for matching (lowercase, e.g. “eb garamond”).

name: String

Face name (name id 4), e.g. “EB Garamond Regular”.

style: String

Style name (name id 2), e.g. “Regular”.

declared: Option<FaceAttributes>

What a stylesheet declared this face to be, overriding what the file says about itself. A declared identity also pins registration to the file’s default instance: a sheet naming one slope and one weight is not describing a variable family’s five.

Implementations

impl FontSource

pub fn from_bytes(bytes: Vec<u8>) -> Result<Self, FontError>

Builds a source from a font file, reading identity from its name table.

impl Clone for FontSource

fn clone(&self) -> FontSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
