Struct Avar 

pub struct Avar<'a> {
    data: FontData<'a>,
}

The avar (Axis Variations) table

Fields

data: FontData<'a>

Implementations

impl<'a> Avar<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

pub fn offset_data(&self) -> FontData<'a>

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &Self

👎Deprecated: just use the base type directly

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

pub fn version(&self) -> MajorMinor

Major version number of the axis variations table — set to 1 or 2. Minor version number of the axis variations table — set to 0.

pub fn axis_count(&self) -> u16

The number of variation axes for this font. This must be the same number as axisCount in the ‘fvar’ table.

pub fn axis_segment_maps(&self) -> VarLenArray<'a, SegmentMaps<'a>>

The segment maps array — one segment map for each axis, in the order of axes specified in the ‘fvar’ table.

pub fn axis_index_map_offset(&self) -> Option<Nullable<Offset32>>

Offset to DeltaSetIndexMap table (may be NULL).

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

Attempt to resolve axis_index_map_offset.

pub fn var_store_offset(&self) -> Option<Nullable<Offset32>>

Offset to ItemVariationStore (may be NULL).

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

Attempt to resolve var_store_offset.

pub fn version_byte_range(&self) -> Range<usize>

pub fn _reserved_byte_range(&self) -> Range<usize>

pub fn axis_count_byte_range(&self) -> Range<usize>

pub fn axis_segment_maps_byte_range(&self) -> Range<usize>

pub fn axis_index_map_offset_byte_range(&self) -> Range<usize>

pub fn var_store_offset_byte_range(&self) -> Range<usize>

Trait Implementations

impl<'a> Clone for Avar<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for Avar<'a>

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instance of Self from the provided data, performing validation.

impl<'a> MinByteRange<'a> for Avar<'a>

fn min_byte_range(&self) -> Range<usize>

fn min_table_bytes(&self) -> &'a [u8]

impl TopLevelTable for Avar<'_>
