Struct Subtable3 

pub struct Subtable3<'a> {
    data: FontData<'a>,
}

The type 3 ‘kern’ subtable.

Fields

data: FontData<'a>

Implementations

impl<'a> Subtable3<'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 glyph_count(&self) -> u16

The number of glyphs in this font.

pub fn kern_value_count(&self) -> u8

The number of kerning values.

pub fn left_class_count(&self) -> u8

The number of left-hand classes.

pub fn right_class_count(&self) -> u8

The number of right-hand classes.

pub fn flags(&self) -> u8

Set to zero (reserved for future use).

pub fn kern_value(&self) -> &'a [BigEndian<i16>]

The kerning values.

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

The left-hand classes.

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

The right-hand classes.

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

The indices into the kernValue array.

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

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

impl Subtable3<'_>

pub fn kerning(&self, left: GlyphId, right: GlyphId) -> Option<i32>

Returns the kerning adjustment for the given pair.

Trait Implementations
