GDEF 1.0

Aliased Type

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

Implementations

impl<'a> Gdef<'a>

pub fn version(&self) -> MajorMinor

The major/minor version of the GDEF table

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

Offset to class definition table for glyph type, from beginning of GDEF header (may be NULL)

pub fn glyph_class_def(&self) -> Option<Result<ClassDef<'a>, ReadError>>

Attempt to resolve glyph_class_def_offset.

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

Offset to attachment point list table, from beginning of GDEF header (may be NULL)

pub fn attach_list(&self) -> Option<Result<AttachList<'a>, ReadError>>

Attempt to resolve attach_list_offset.

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

Offset to ligature caret list table, from beginning of GDEF header (may be NULL)

pub fn lig_caret_list(&self) -> Option<Result<LigCaretList<'a>, ReadError>>

Attempt to resolve lig_caret_list_offset.

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

Offset to class definition table for mark attachment type, from beginning of GDEF header (may be NULL)

pub fn mark_attach_class_def(&self) -> Option<Result<ClassDef<'a>, ReadError>>

Attempt to resolve mark_attach_class_def_offset.

pub fn mark_glyph_sets_def_offset(&self) -> Option<Nullable<Offset16>>

Offset to the table of mark glyph set definitions, from beginning of GDEF header (may be NULL)

pub fn mark_glyph_sets_def( &self, ) -> Option<Result<MarkGlyphSets<'a>, ReadError>>

Attempt to resolve mark_glyph_sets_def_offset.

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

Offset to the Item Variation Store table, from beginning of GDEF header (may be NULL)

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

Attempt to resolve item_var_store_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 Gdef<'a>

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

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

impl TopLevelTable for Gdef<'_>

const TAG: Tag

GDEF

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.
