Aliased Type

struct Hvar<'a> { /* private fields */ }

Implementations

impl<'a> Hvar<'a>

pub fn version(&self) -> MajorMinor

Major version number of the horizontal metrics variations table — set to 1. Minor version number of the horizontal metrics variations table — set to 0.

pub fn item_variation_store_offset(&self) -> Offset32

Offset in bytes from the start of this table to the item variation store table.

pub fn item_variation_store(&self) -> Result<ItemVariationStore<'a>, ReadError>

Attempt to resolve item_variation_store_offset.

pub fn advance_width_mapping_offset(&self) -> Nullable<Offset32>

Offset in bytes from the start of this table to the delta-set index mapping for advance widths (may be NULL).

pub fn advance_width_mapping( &self, ) -> Option<Result<DeltaSetIndexMap<'a>, ReadError>>

Attempt to resolve advance_width_mapping_offset.

pub fn lsb_mapping_offset(&self) -> Nullable<Offset32>
