You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: simple_console_backing.rs
    path of file: ./repos/bracket-lib/bracket-terminal/src/hal/webgpu/backing
    
    the code of the file until where you have to start completion: //! Maps a Simple Console to WGPU backing

use super::index_array_helper::IndexBuffer;
use super::vertex_array_helper::FloatBuffer;
use crate::hal::{
    scaler
    
    fn init_buffer_for_console(vertex_capacity: usize) -> FloatBuffer<f32> {
        FloatBuffer::<f32>::new(
            &[3, 4, 4, 2], // Pos, FG, BG, TexPos
            vertex_capacity,
            BufferUsages::VERTEX,
        )
    }
