Implementations
source§impl<'a> FontCollection<'a>
impl<'a> FontCollection<'a>
sourcepub fn from_bytes<B>(bytes: B) -> Result<FontCollection<'a>, Error>where
B: Into<SharedBytes<'a>>,
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.
sourcepub fn into_font(self) -> Result<Font<'a>, Error>
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.
sourcepub fn font_at(&self, i: usize) -> Result<Font<'a>, Error>
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.
sourcepub fn into_fonts(self) -> IntoFontsIter<'a>
pub fn into_fonts(self) -> IntoFontsIter<'a>
Converts self
into an Iterator
yielding each Font
that exists
within the collection.
