Struct rusttype::FontCollection

pub struct FontCollection<'a>(_);

A collection of fonts read straight from a font file's data. The data in the collection is not validated. This structure may or may not own the font data.

Methods

impl<'a> FontCollection<'a>

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

Constructs a font collection from an array of bytes, typically loaded from a font file. 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.

pub fn into_font(self) -> Option<Font<'a>>

In the common case that a font collection consists of only one font, this function consumes this font collection and turns it into a font. If this is not the case, or the font is not valid (read: not supported by this library), None is returned.

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

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.

Important traits for IntoFontsIter<'a>

impl<'a> Iterator for IntoFontsIter<'a> type Item = Font<'a>;

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

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