Struct Subtable

pub struct Subtable<'a> {
    pub horizontal: bool,
    pub variable: bool,
    pub has_cross_stream: bool,
    pub has_state_machine: bool,
    pub tuple_count: u32,
    pub format: Format<'a>,
}

A kerning subtable.

Fields

horizontal: bool

Indicates that subtable is for horizontal text.

variable: bool

Indicates that subtable is variable.

has_cross_stream: bool

Indicates that subtable has a cross-stream values.

has_state_machine: bool

Indicates that subtable uses a state machine.

In this case glyphs_kerning() will return None.

tuple_count: u32

The tuple count.

This value is only used with variation fonts and should be 0 for all other fonts.

format: Format<'a>

Subtable format.

Implementations

impl<'a> Subtable<'a>

pub fn glyphs_kerning(&self, left: GlyphId, right: GlyphId) -> Option<i16>

Returns kerning for a pair of glyphs.

Returns None in case of state machine based subtable.

Trait Implementations

impl<'a> Clone for Subtable<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Subtable<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
