Expand description

Reasons why a loader might fail to load a font.

Variants§

§

UnknownFormat

The data was of a format the loader didn’t recognize.

§

NoSuchFontInCollection

Attempted to load an invalid index in a TrueType or OpenType font collection.

For example, if a .ttc file has 2 fonts in it, and you ask for the 5th one, you’ll get this error.

§

Parse

Attempted to load a malformed or corrupted font.

§

NoFilesystem

Attempted to load a font from the filesystem, but there is no filesystem (e.g. in WebAssembly).

§

Io(Error)

A disk or similar I/O error occurred while attempting to load the font.
