vars.insert("PascalName", "CameraDriver");

let engine = TemplateEngine::default();
let rendered = engine.render("drivers/sensor.rs.template", &vars)?;

pub async fn render_to_file( &self, template_path: &str, output_path: impl AsRef<Path>, variables: &HashMap<&str, &str>, ) -> Result<()>

Render a template and write it to a file

Arguments

• template_path - Path to template file relative to template_dir
• output_path - Destination file path
