Implementations

source§

impl<'a> FontCollection<'a>

source

pub fn from_bytes<B>(bytes: B) -> Result<FontCollection<'a>, Error>
where B: Into<SharedBytes<'a>>,

Constructs a font collection from an array of bytes, typically loaded from a font file, which may be a single font or a TrueType Collection holding a number of fonts. This array may be owned (e.g. Vec<u8>), or borrowed (&[u8]). As long as From<T> is implemented for Bytes for some type T, T can be used as input.

This returns an error if bytes does not seem to be font data in a format we recognize.

source

pub fn into_font(self) -> Result<Font<'a>, Error>

If this FontCollection holds a single font, or a TrueType Collection containing only one font, return that as a Font. The FontCollection is consumed.

If this FontCollection holds multiple fonts, return a CollectionContainsMultipleFonts error.

If an error occurs, the FontCollection is lost, since this function takes ownership of it, and the error values don’t give it back. If that is a problem, use the font_at or into_fonts methods instead, which borrow the FontCollection rather than taking ownership of it.

source

pub fn font_at(&self, i: usize) -> Result<Font<'a>, Error>

Gets the font at index i in the font collection, if it exists and is valid. The produced font borrows the font data that is either borrowed or owned by this font collection.

source

pub fn into_fonts(self) -> IntoFontsIter<'a>

Converts self into an Iterator yielding each Font that exists within the collection.
