Struct FeatureSetting 

pub struct FeatureSetting {
    pub tag: [u8; 4],
    pub value: u32,
}

One OpenType feature the run asks the face for: the tag and the value, where 0 turns the feature off and 1 turns it on. A feature with alternates takes the number of the alternate.

Fields

tag: [u8; 4]

The four-byte OpenType feature tag, e.g. onum.

value: u32

What the feature is set to.
