Struct Cmap8 

pub struct Cmap8<'a> { /* private fields */ }

cmap Format 8: mixed 16-bit and 32-bit coverage

Implementations

impl<'a> Cmap8<'a>

pub const MIN_SIZE: usize

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) -> &Self

👎Deprecated:

just use the base type directly

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.

pub fn format(&self) -> u16

Subtable format; set to 8.

pub fn length(&self) -> u32

Byte length of this subtable (including the header)

pub fn language(&self) -> u32

For requirements on use of the language field, see “Use of the language field in ‘cmap’ subtables” in this document.

pub fn is32(&self) -> &'a [u8]

Tightly packed array of bits (8K bytes total) indicating whether the particular 16-bit (index) value is the start of a 32-bit character code

pub fn num_groups(&self) -> u32

Number of groupings which follow

pub fn groups(&self) -> &'a [SequentialMapGroup]

Array of SequentialMapGroup records.

pub fn format_byte_range(&self) -> Range<usize>

pub fn reserved_byte_range(&self) -> Range<usize>

pub fn length_byte_range(&self) -> Range<usize>

pub fn language_byte_range(&self) -> Range<usize>

pub fn is32_byte_range(&self) -> Range<usize>

pub fn num_groups_byte_range(&self) -> Range<usize>

pub fn groups_byte_range(&self) -> Range<usize>

Trait Implementations

impl<'a> Clone for Cmap8<'a>

fn clone(&self) -> Cmap8<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for Cmap8<'a>

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

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

impl<'a> MinByteRange<'a> for Cmap8<'a>

fn min_byte_range(&self) -> Range<usize>

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