Struct Cmap13 

pub struct Cmap13<'a> {
    data: FontData<'a>,
}

cmap Format 13: Many-to-one range mappings

Fields

data: FontData<'a>

Implementations

impl<'a> Cmap13<'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 13.

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 num_groups(&self) -> u32

Number of groupings which follow

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

Array of ConstantMapGroup 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 num_groups_byte_range(&self) -> Range<usize>

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

impl<'a> Cmap13<'a>

pub fn map_codepoint(&self, codepoint: impl Into<u32>) -> Option<GlyphId>

Maps a codepoint to a nominal glyph identifier.

pub fn iter(&self) -> Cmap13Iter<'a>

Returns an iterator over all (codepoint, glyph identifier) pairs in the subtable.

Malicious and malformed fonts can produce a large number of invalid pairs. Use Self::iter_with_limits to generate a pruned sequence that is limited to reasonable values.

pub fn iter_with_limits(&self, limits: CmapIterLimits) -> Cmap13Iter<'a>

Returns an iterator over all (codepoint, glyph identifier) pairs in the subtable within the given limits.

Trait Implementations

impl<'a> Clone for Cmap13<'a>

fn clone(&self) -> Cmap13<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for Cmap13<'a>

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

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

impl Format<u16> for Cmap13<'_>

const FORMAT: u16 = 13

The format value for this table.

impl<'a> MinByteRange<'a> for Cmap13<'a>

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

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