Struct speedy2d::font::FontFamily

pub struct FontFamily { /* private fields */ }

A collection of fonts, in decreasing order of priority. When laying out text, if a codepoint cannot be found in the first font in the list, the subsequent fonts will also be searched.

Implementations

impl FontFamily

pub fn new(fonts: Vec<Font>) -> Self

Instantiates a new font family, containing the specified fonts in decreasing order of priority.

Trait Implementations

impl Clone for FontFamily

fn clone(&self) -> FontFamily

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FontFamily

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for FontFamily

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<FontFamily> for FontFamily

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TextLayout for FontFamily

fn lookup_glyph_for_codepoint(&self, codepoint: char) -> Option<FontGlyph>

Returns the glyph corresponding to the provided codepoint. If the glyph cannot be found, None is returned.

fn empty_line_vertical_metrics(&self, scale: f32) -> LineVerticalMetrics

The default metrics of a line which contains no characters.

fn layout_text(
    &self,
    text: &str,
    scale: f32,
    options: TextOptions
) -> Rc<FormattedTextBlock>

Lays out a block of text with the specified scale and options. The result may be passed to Graphics2D::draw_text.

fn layout_text_from_unindexed_codepoints(
    &self,
    unindexed_codepoints: &[char],
    scale: f32,
    options: TextOptions
) -> Rc<FormattedTextBlock>

Lays out a block of text with the specified scale and options. The result may be passed to Graphics2D::draw_text.

fn layout_text_from_codepoints(
    &self,
    codepoints: &[Codepoint],
    scale: f32,
    options: TextOptions
) -> Rc<FormattedTextBlock>

Lays out a block of text with the specified scale and options. The result may be passed to Graphics2D::draw_text.
