Struct VariationIndex 

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

Variation index table

Fields

data: FontData<'a>

Implementations

impl<'a> VariationIndex<'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 delta_set_outer_index(&self) -> u16

A delta-set outer index — used to select an item variation data subtable within the item variation store.

pub fn delta_set_inner_index(&self) -> u16

A delta-set inner index — used to select a delta-set row within an item variation data subtable.

pub fn delta_format(&self) -> DeltaFormat

Format, = 0x8000

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

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

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