Struct FontFace 

pub struct FontFace { /* private fields */ }

Immutable font bytes and collection face index, shared across scene snapshots.

Loading never performs font discovery or I/O. Layout reparses the retained bytes; parser allocations and caller input are not a hard RSS budget.

Implementations

impl FontFace

pub fn from_bytes( bytes: Vec<u8>, face_index: u32, ) -> Result<Self, ValidationError>

Validates an OpenType/TrueType face before retaining its bytes. Invalid data or face indices fail without constructing a resource.

pub fn byte_len(&self) -> usize

Retained source payload, excluding allocation overhead and parser scratch.

pub fn index(&self) -> u32

Index of the retained face in its source collection.

pub fn library(&self) -> Result<FontLibrary, ValidationError>

Creates an explicit paragraph font snapshot without system discovery.

Trait Implementations

impl Asset for FontFace

Available on crate feature text only.

const KIND: &'static str = "font"

Human-readable resource category retained by load diagnostics.

fn decode(bytes: &[u8], _: &LoadContext) -> Result<Self>

Decodes bounded input without requiring a rendering device. Implementations must be deterministic for these bytes/context; recursive resource dependency graphs are not a supported decoder contract.

fn retained_bytes(&self) -> usize

Logical decoded payload charge; custom heap-owning assets should override. At least the encoded input length is charged regardless of this value.

impl Clone for FontFace

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontFace

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

Formats the value using the given formatter.
