Trait for drawing text with different alignments (centered or right-aligned)

Required Methods

fn draw_centered_text( &mut self, text: &str, x: i32, y: i32, font_size: i32, color: impl Into<Color>, )

fn draw_right_aligned_text( &mut self, text: &str, x: i32, y: i32, font_size: i32, color: impl Into<Color>, )

fn measure_text_ext(&mut self, text: &str, font_size: i32) -> (i32, i32)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl TextAlignment for RaylibDrawHandle<'_>

Implement the TextAlignment trait for RaylibDrawHandle to enable custom text drawing

fn draw_centered_text( &mut self, text: &str, x: i32, y: i32, font_size: i32, color: impl Into<Color>, )

Draw text centered at the specified (x, y) position

Example:

use raylib::prelude::*;
use raylib_ext::*;

fn main() {
  let (mut rl, thread) = init()
    .size(640, 480)
    .title("Hello, World")
    .build();

  while !rl.window_should_close() {
    let mut d = rl.begin_drawing(&thread);

    d.clear_background(Color::WHITE);

    // Draws text where (x, y) is in the middle of the text instead of top-left
    d.draw_centered_text("Hello, world!", 12, 12, 20, Color::BLACK);
  }
}

fn draw_right_aligned_text( &mut self, text: &str, x: i32, y: i32, font_size: i32, color: impl Into<Color>, )

Draw text right-aligned at the specified (x, y) position

Example:

use raylib::prelude::*;
use raylib_ext::*;

fn main() {
  let (mut rl, thread) = init()
    .size(640, 480)
    .title("Hello, World")
    .build();

  while !rl.window_should_close() {
    let mut d = rl.begin_drawing(&thread);

    d.clear_background(Color::WHITE);

    // Draws text where (x, y) is in the top-right corner instead of top-left
    d.draw_right_aligned_text("Hello, world!", 12, 12, 20, Color::BLACK);
  }
}

fn measure_text_ext(&mut self, text: &str, font_size: i32) -> (i32, i32)
