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: lines.rs
    path of file: ./repos/bevy/examples/3d
    
    the code of the file until where you have to start completion: //! Create a custom material to draw basic lines in 3D

use bevy::{
    pbr::{MaterialPipeline, MaterialPipelineKey},
    prelude::*,
    reflect::TypePath,
    render::{
        mesh::{MeshVertexBuffer
    
    fn from(line: LineStrip) -> Self {
        Mesh::new(
            // This tells wgpu that the positions are a list of points
            // where a line will be drawn between each consecutive point
            PrimitiveTopology::LineStrip,
            RenderAssetUsages::RENDER_WORLD,
        )
        // Add the point positions as an attribute
        .with_inserted_attribute(Mesh::ATTRIBUTE_POSITION, line.points)
    }
