Trait Implementations

impl Clone for Font

fn clone(&self) -> Font

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Font

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

Formats the value using the given formatter.

impl Hash for Font

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 for Font

fn eq(&self, other: &Self) -> 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 Font

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 ) -> 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 ) -> 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 ) -> FormattedTextBlock

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