Struct Cmap6 

pub struct Cmap6<'a> {
    data: FontData<'a>,
}

cmap Format 6: Trimmed table mapping

Fields

data: FontData<'a>

Implementations

impl<'a> Cmap6<'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

Format number is set to 6.

pub fn length(&self) -> u16

This is the length in bytes of the subtable.

pub fn language(&self) -> u16

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

pub fn first_code(&self) -> u16

First character code of subrange.

pub fn entry_count(&self) -> u16

Number of character codes in subrange.

pub fn glyph_id_array(&self) -> &'a [BigEndian<u16>]

Array of glyph index values for character codes in the range.

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

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

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

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

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

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

impl<'a> Cmap6<'a>

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

pub fn iter(&self) -> Cmap6Iter<'a>

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

Trait Implementations

impl<'a> Clone for Cmap6<'a>

fn clone(&self) -> Cmap6<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for Cmap6<'a>

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

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

impl Format<u16> for Cmap6<'_>

const FORMAT: u16 = 6

The format value for this table.

impl<'a> MinByteRange<'a> for Cmap6<'a>

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

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