pub struct FontDataRef<'a> { /* private fields */ }

Reference to the content of a font file.

Implementations

impl<'a> FontDataRef<'a>

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

Creates font data from the specified bytes. Returns None if the bytes cannot trivially be determined to represent a font.

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.

Trait Implementations

impl<'a> Clone for FontDataRef<'a>

fn clone(&self) -> FontDataRef<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> IntoIterator for FontDataRef<'a>

type IntoIter = Fonts<'a>
