Font capital letters variant features.

Variants

Auto = 0

No caps variant.

SmallCaps = 1

Enable small caps alternative for lowercase letters.

This corresponds to OpenType smcp feature.

AllSmallCaps = 2

Enable small caps alternative for lower and upper case letters.

This corresponds to OpenType smcp and c2sc features.

Petite = 3

Enable petite caps alternative for lowercase letters.

This corresponds to OpenType pcap feature.

AllPetite = 4

Enable petite caps alternative for lower and upper case letters.

This corresponds to OpenType pcap and c2pc features.

Unicase = 5

Enables unicase, using small caps for upper case letters mixed with normal lowercase letters.

This corresponds to OpenType unic feature.

TitlingCaps = 6

Enable title caps alternatives. This uses alternative uppercase glyphs designed for all uppercase words.

This corresponds to OpenType titl feature.

impl PartialEq for CapsVariant

fn eq(&self, other: &CapsVariant) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
