Type Alias Cff2Header

pub type Cff2Header<'a> = TableRef<'a, Cff2HeaderMarker>;

Compact Font Format (CFF) version 2 table header

Aliased Type

struct Cff2Header<'a> { /* private fields */ }

Implementations

impl<'a> Cff2Header<'a>

pub fn major_version(&self) -> u8

Format major version (set to 2).

pub fn minor_version(&self) -> u8

Format minor version (set to 0).

pub fn header_size(&self) -> u8

Header size (bytes).

pub fn top_dict_length(&self) -> u16

Length of Top DICT structure in bytes.

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

Padding bytes before the start of the Top DICT.

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

Data containing the Top DICT.

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

Remaining table 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 Cff2Header<'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.
