Type Alias Index2

pub type Index2<'a> = TableRef<'a, Index2Marker>;

An array of variable-sized objects in a CFF2 table.

Aliased Type

struct Index2<'a> { /* private fields */ }

Implementations

impl<'a> Index2<'a>

pub fn size_in_bytes(&self) -> Result<usize, ReadError>

Returns the total size in bytes of the index table.

pub fn get_offset(&self, index: usize) -> Result<usize, Error>

Returns the offset of the object at the given index.

pub fn get(&self, index: usize) -> Result<&'a [u8], Error>

Returns the data for the object at the given index.

impl<'a> Index2<'a>

pub fn count(&self) -> u32

Number of objects stored in INDEX.

pub fn off_size(&self) -> u8

Object array element size.

pub fn offsets(&self) -> &'a [u8]

Bytes containing count + 1 offsets each of off_size.

pub fn data(&self) -> &'a [u8]

Array containing the object data.

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 Index2<'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.
