Type Alias Ankr

pub type Ankr<'a> = TableRef<'a, AnkrMarker>;

The anchor point table.

Aliased Type

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

Implementations

impl<'a> Ankr<'a>

pub fn version(&self) -> u16

Version number (set to zero).

pub fn flags(&self) -> u16

Flags (currently unused; set to zero).

pub fn lookup_table_offset(&self) -> Offset32

Offset to the table’s lookup table; currently this is always 0x0000000C.

Lookup values are two byte offsets into the glyph data table.

pub fn lookup_table(&self) -> Result<LookupU16<'a>, ReadError>

Attempt to resolve lookup_table_offset.

pub fn glyph_data_table_offset(&self) -> u32

Offset to the glyph data table.

impl<'a> Ankr<'a>

pub fn anchor_points( &self, glyph_id: GlyphId, ) -> Result<&'a [AnchorPoint], ReadError>

Returns the set of anchor points for the given glyph.

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 Ankr<'a>

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

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

impl TopLevelTable for Ankr<'_>

const TAG: Tag

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.
