Struct FontBlob

Source

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

Expand description

Wrapper for font data that can be created from multiple sources without unnecessary copies.

Chrome equivalent: the data source for a FontFace — can be a static buffer (bundled font) or dynamically loaded bytes (web font).

Trait Implementations§

Source §

impl From<&'static [u8]> for FontBlob

Source §

fn from(data: &'static [u8]) -> Self

Zero-copy: wraps the static pointer in an Arc (no data copy). Ideal for include_bytes!().

Source §

impl From<Arc<Vec<u8>>> for FontBlob

Source §

fn from(data: Arc<Vec<u8>>) -> Self

Already shared — wrap directly.

Source §

impl From<Vec<u8>> for FontBlob

Source §

fn from(data: Vec<u8>) -> Self

One allocation: Vec → Box<u8> → Arc.
