Enum StandardFont 

#[repr(u8)]
pub enum StandardFont {
    Courier = 0,
    CourierBold = 1,
    CourierBoldOblique = 2,
    CourierOblique = 3,
    Helvetica = 4,
    HelveticaBold = 5,
    HelveticaBoldOblique = 6,
    HelveticaOblique = 7,
    Times = 8,

    Symbol = 12,
    Dingbats = 13,
}

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

impl StandardFont

pub fn index(self) -> usize

The index into the base-14 tables.

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

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

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.

pub fn is_fixed(self) -> bool

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

pub fn is_stylable(self) -> bool

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

Trait Implementations

impl Clone for StandardFont

fn clone(&self) -> StandardFont

Returns a duplicate of the value.

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

impl Ord for StandardFont

fn cmp(&self, other: &StandardFont) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
