Struct GlyphCoverage 

pub struct GlyphCoverage {
    total_unique: usize,
    covered: usize,
    missing_chars: Vec<char>,
}

Statistics about glyph coverage for a given text.

This struct provides information about how well a font supports the characters in a text string, useful for determining if font fallbacks are needed.

Fields

total_unique: usize

Total number of unique characters in the analyzed text

covered: usize

Number of characters that have glyphs in the font

missing_chars: Vec<char>

List of characters that are missing from the font

Implementations

impl GlyphCoverage

pub fn coverage_percent(&self) -> f32

Returns the percentage of characters covered by the font (0-100).

pub fn is_complete(&self) -> bool

Returns true if all characters are covered (100% coverage).

pub fn missing_chars(&self) -> &[char]

Returns the list of missing characters.

pub fn covered_count(&self) -> usize

Returns the number of covered characters.

pub fn total_count(&self) -> usize

Returns the total number of unique characters analyzed.
