Struct IndexSubtable3 

pub struct IndexSubtable3<'a> {
    data: FontData<'a>,
    last_glyph_index: GlyphId16,
    first_glyph_index: GlyphId16,
}

IndexSubTable3: variable-metrics glyphs with 2-byte offsets.

Fields

data: FontData<'a>

last_glyph_index: GlyphId16

first_glyph_index: GlyphId16

Implementations

impl<'a> IndexSubtable3<'a>

pub fn read( data: FontData<'a>, last_glyph_index: GlyphId16, first_glyph_index: GlyphId16, ) -> Result<Self, ReadError>

A constructor that requires additional arguments.

This type requires some external state in order to be parsed.

impl<'a> IndexSubtable3<'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 index_format(&self) -> u16

Format of this IndexSubTable.

pub fn image_format(&self) -> u16

Format of EBDT image data.

pub fn image_data_offset(&self) -> u32

Offset to image data in EBDT table.

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

pub(crate) fn last_glyph_index(&self) -> GlyphId16

pub(crate) fn first_glyph_index(&self) -> GlyphId16

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

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

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

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

Trait Implementations

impl<'a> Clone for IndexSubtable3<'a>

fn clone(&self) -> IndexSubtable3<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontReadWithArgs<'a> for IndexSubtable3<'a>

fn read_with_args( data: FontData<'a>, args: &(GlyphId16, GlyphId16), ) -> Result<Self, ReadError>

read an item, using the provided args.

impl Format<u16> for IndexSubtable3<'_>

const FORMAT: u16 = 3

The format value for this table.

impl<'a> MinByteRange<'a> for IndexSubtable3<'a>

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

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

impl ReadArgs for IndexSubtable3<'_>

type Args = (GlyphId16, GlyphId16)
