Struct Face 

pub struct Face {
    pub family: Option<u16>,
    pub italic: Option<bool>,
    pub weight: Option<u16>,
}

The face ::first-line asks its runs for: a family, a slope and a weight, each one set only where the rule set it.

A run of the opening line keeps what the rule left alone, so font-style: italic over a bold emphasis picks the bold italic rather than the regular one. The family is a face of the family asked for, because a family is named once in the style tree and carried here by one of its cuts.

Fields

family: Option<u16>

A face of the family the line is set in.

italic: Option<bool>

Whether the line is italic.

weight: Option<u16>

Weight on the CSS 1 to 1000 scale.
