Type Alias Lookup8

pub type Lookup8<'a> = TableRef<'a, Lookup8Marker>;

Trimmed array format. The lookup data is a simple trimmed array indexed by glyph index.

Aliased Type

pub struct Lookup8<'a> {
    pub(crate) shape: Lookup8Marker,
    pub(crate) data: FontData<'a>,
}

Fields

shape: Lookup8Marker

data: FontData<'a>

Implementations

impl<'a> Lookup8<'a>

pub fn format(&self) -> u16

Format number is set to 8.

pub fn first_glyph(&self) -> u16

First glyph index included in the trimmed array.

pub fn glyph_count(&self) -> u16

Total number of glyphs (equivalent to the last glyph minus the value of firstGlyph plus 1).

pub fn value_array(&self) -> &'a [BigEndian<u16>]

The lookup values (indexed by the glyph index minus the value of firstGlyph). Entries in the value array must be two bytes.

impl Lookup8<'_>

pub fn value<T: LookupValue>(&self, index: u16) -> Result<T, ReadError>
