Enum pango::CoverageLevel
source · #[non_exhaustive]pub enum CoverageLevel {
None,
Fallback,
Approximate,
Exact,
}
Expand description
CoverageLevel
is used to indicate how well a font can
represent a particular Unicode character for a particular script.
Variants (Non-exhaustive)§
This enum is marked as 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.
None
The character is not representable with the font.
Fallback
The character is represented in a way that may be comprehensible but is not the correct graphical form. For instance, a Hangul character represented as a a sequence of Jamos, or a Latin transliteration of a Cyrillic word.
Approximate
The character is represented as basically the correct graphical form, but with a stylistic variant inappropriate for the current script.
Exact
The character is represented as the correct graphical form.
