Enum Coverage

pub enum Coverage<'a> {
    Format1 {
        glyphs: LazyArray16<'a, GlyphId>,
    },
    Format2 {
        records: LazyArray16<'a, RangeRecord>,
    },
}

A Coverage Table.

Variants

Format1

Fields

glyphs: LazyArray16<'a, GlyphId>

Array of glyph IDs. Sorted.

Format2

Fields

records: LazyArray16<'a, RangeRecord>

Array of glyph ranges. Ordered by RangeRecord.start.

Implementations

impl<'a> Coverage<'a>

pub fn contains(&self, glyph: GlyphId) -> bool

Checks that glyph is present.

pub fn get(&self, glyph: GlyphId) -> Option<u16>

Returns the coverage index of the glyph or None if it is not covered.

Trait Implementations

impl<'a> Clone for Coverage<'a>

fn clone(&self) -> Coverage<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Coverage<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
