Implementations

impl<'a> FontDataRef<'a>

pub fn new(data: &'a [u8]) -> Option<Self>

pub fn is_collection(&self) -> bool

Returns true if the data represents a font collection.

pub fn data(&self) -> &'a [u8]

Returns the underlying data.

pub fn len(&self) -> usize

Returns the number of available fonts.

pub fn is_empty(&self) -> bool

Returns true if there are no available fonts.

pub fn get(&self, index: usize) -> Option<FontRef<'a>>

Returns the font at the specified index.

pub fn fonts(&self) -> Fonts<'a>

Returns an iterator over the available fonts.
