Type Alias AnchorFormat3

pub type AnchorFormat3<'a> = TableRef<'a, AnchorFormat3Marker>;

Anchor Table Format 3: Design Units Plus Device or VariationIndex Tables

Aliased Type

struct AnchorFormat3<'a> { /* private fields */ }

Implementations

impl<'a> AnchorFormat3<'a>

pub fn anchor_format(&self) -> u16

Format identifier, = 3

pub fn x_coordinate(&self) -> i16

Horizontal value, in design units

pub fn y_coordinate(&self) -> i16

Vertical value, in design units

pub fn x_device_offset(&self) -> Nullable<Offset16>

Offset to Device table (non-variable font) / VariationIndex table (variable font) for X coordinate, from beginning of Anchor table (may be NULL)

pub fn x_device(&self) -> Option<Result<DeviceOrVariationIndex<'a>, ReadError>>

Attempt to resolve x_device_offset.

pub fn y_device_offset(&self) -> Nullable<Offset16>

Offset to Device table (non-variable font) / VariationIndex table (variable font) for Y coordinate, from beginning of Anchor table (may be NULL)

pub fn y_device(&self) -> Option<Result<DeviceOrVariationIndex<'a>, ReadError>>

Attempt to resolve y_device_offset.

impl<'a, T> TableRef<'a, T>

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) -> &T

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.

Trait Implementations

impl<'a> FontRead<'a> for AnchorFormat3<'a>

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

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

impl<'a, T: Clone> Clone for TableRef<'a, T>

fn clone(&self) -> TableRef<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.
