Expand description

One of the fourteen standard fonts.

The discriminants are load-bearing, not cosmetic. Within a family the order is Regular, Bold, BoldOblique, Oblique — so index % 4 decides the style and index + 1 / +2 / +3 is how a style is applied to a family . Changing the order silently changes substitution.

Variants§

§

Courier = 0

Courier.

§

CourierBold = 1

Courier-Bold.

§

CourierBoldOblique = 2

Courier-BoldOblique.

§

CourierOblique = 3

Courier-Oblique.

§

Helvetica = 4

Helvetica.

§

HelveticaBold = 5

Helvetica-Bold.

§

HelveticaBoldOblique = 6

Helvetica-BoldOblique.

§

HelveticaOblique = 7

Helvetica-Oblique.

§

Times = 8

Times-Roman.

§

TimesBold = 9

Times-Bold.

§

TimesBoldOblique = 10

Times-BoldItalic. Note the family asymmetry: Courier and Helvetica say Oblique where Times says Italic.

§

TimesOblique = 11

Times-Italic.

§

Symbol = 12

Symbol.

§

Dingbats = 13

ZapfDingbats.

Implementations§

Source§

impl StandardFont

Source

pub fn index(self) -> usize

The index into the base-14 tables.

Source

pub fn from_index(i: usize) -> Option<StandardFont>

Build from an index, for the arithmetic of the former working note step 10.

Source

pub fn is_symbolic(self) -> bool

Symbol and ZapfDingbats are the two whose glyphs are not Latin text, which changes both their default flags and their default encoding.

Source

pub fn is_fixed(self) -> bool

The four Couriers, whose every glyph is 600 units wide.

Source

pub fn is_stylable(self) -> bool

Can a style be applied to this index by arithmetic? Only the three family heads can (IsStylableBaseFont).
