Enum FontGlyphOrderError 

#[non_exhaustive]
pub enum FontGlyphOrderError {
    ReadError(ReadError),
    MissingNames,
    BadGlyphOrder(GlyphOrderError),
}

An error that occurs when extracting a glyph order from a font file.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ReadError(ReadError)

Failed to read font data

MissingNames

Post table is missing glyph names

BadGlyphOrder(GlyphOrderError)

Glyphs were present but not a valid glyph order.
