+#### Querying shader compilation errors
+
+Wgpu now supports querying [shader compilation info](https://www.w3.org/TR/webgpu/#dom-gpushadermodule-getcompilationinfo).
+
+This allows you to get more structured information about compilation errors, warnings and info:
+```rust
+...
+let lighting_shader = ctx.device.create_shader_module(include_wgsl!("lighting.wgsl"));
+let compilation_info = lighting_shader.get_compilation_info().await;
+for message in compilation_info
+    .messages
+    .iter()
+    .filter(|m| m.message_type == wgpu::CompilationMessageType::Error)
+{
+    let line = message.location.map(|l| l.line_number).unwrap_or(1);
+    println!("Compile error at line {line}");
+}
