Expand description

This Trait specifies the font callbacks that harfbuzz uses when asked to draw a glyph.

Required Methods§

Source

fn move_to(&mut self, st: &DrawState, to_x: f32, to_y: f32)

Source

fn line_to(&mut self, st: &DrawState, to_x: f32, to_y: f32)

Source

fn quadratic_to( &mut self, st: &DrawState, control_x: f32, control_y: f32, to_x: f32, to_y: f32, )

Source

fn cubic_to( &mut self, st: &DrawState, control1_x: f32, control1_y: f32, control2_x: f32, control2_y: f32, to_x: f32, to_y: f32, )

Source

fn close_path(&mut self, st: &DrawState)

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
