Struct write_fonts::tables::gpos::PositionChainContext

pub struct PositionChainContext(_);

A typed wrapper around a shared table.

This is used so that we can associate the correct lookup ids for lookups that are shared between GPOS/GSUB.

You can access the inner type via Deref or the as_inner method.

Implementations

impl PositionChainContext

pub fn as_inner(&self) -> &ChainedSequenceContext

Return a reference to the inner type.

Trait Implementations

impl Clone for PositionChainContext

fn clone(&self) -> PositionChainContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PositionChainContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PositionChainContext

fn default() -> PositionChainContext

Returns the “default value” for a type.

impl Deref for PositionChainContext

type Target = ChainedSequenceContext

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for PositionChainContext

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl FontWrite for PositionChainContext

fn write_into(&self, writer: &mut TableWriter)

Write our data and information about offsets into this TableWriter.

fn table_type(&self) -> TableType

The type of this table.

impl From<ChainedSequenceContext> for PositionChainContext

fn from(src: ChainedSequenceContext) -> PositionChainContext

Converts to this type from the input type.

impl<'a> FromObjRef<ChainedSequenceContext<'a>> for PositionChainContext

fn from_obj_ref(obj: &ChainedSequenceContext<'a>, _data: FontData<'_>) -> Self

Convert from to an instance of Self, using the provided data to resolve offsets.

impl<'a> FromTableRef<ChainedSequenceContext<'a>> for PositionChainContext

fn from_table_ref(from: &T) -> Self

impl LookupSubtable for PositionChainContext

const TYPE: LookupType = _

The lookup type of this layout subtable.

impl Validate for PositionChainContext

fn validate_impl(&self, ctx: &mut ValidationCtx)

Validate this table.

fn validate(&self) -> Result<(), ValidationReport>

Ensure that this table is well-formed, reporting any errors.
